<p><em>People’s Bridge of the Sun</em> is an immersive public artwork by David Ocelotl Garcia that transforms the 51st Avenue bridge at Denver’s National Western Center into a layered expression of community, history, and place. Ceramic, bronze, cement, glass, and steel come together across the 250-foot-long installation, surrounding visitors with color, texture, symbolic imagery, and forms inspired by the natural world.</p>



<p>The artwork connects the Mexican heritage of the Globeville and Elyria-Swansea neighborhoods with the larger environment and the history of the First Nations of this land. Sculptural trees, hand-shaped metal leaves, ceramic self-portraits, monumental bronze faces, and mosaic-accented concrete forms reflect the belief that people come from many cultural, spiritual, and ethnic backgrounds while remaining part of one shared community.</p>



<p>Community participation is embedded throughout the work. Hundreds of children and adults contributed hand tracings, portraits, and ideas, working alongside artists, designers, and fabricators from across the country. Completed in 2022, the bridge creates both a physical connection across the South Platte River and a lasting gathering place that links the past, present, and future through collective creativity and human connection.</p>

<p><em>Love Language</em>, or <em>Yolotl Tlahtoa</em>, is a public artwork by David Ocelotl Garcia that explores the power, beauty, and responsibility of expression. Inspired by the Nahuatl language and the visual traditions of Latin, Chicano, Mexicano, Native American, and Indigenous cultures, the work celebrates the many ways our words, ideas, and aspirations shape both personal identity and the communities around us.</p>



<p>The sculpture takes the form of a butterfly filled with hearts, mouths, speech scrolls, and patterns drawn from cultures around the world. Together, these symbols represent the voices of students and the movement of ideas from one person to another. The imagery also creates space for reflection on social and environmental concerns, self-expression, and the importance of speaking with intention while listening with curiosity.</p>



<p>Fabricated from aluminum and stainless steel, the 40-foot-long installation stretches across a prominent pedestrian route near Meriam Library at Chico State. Its scale and layered imagery create a strong visual landmark while inviting viewers to consider how language can connect people, carry meaning, and help turn goals and dreams into action.</p>

<p><em>Nautical Swing</em> riffs on the architecture of the site’s former Navy base. The artwork provides a place where up to a dozen people can relax, converse, and enjoy the spectacular view of San Francisco, Oakland, and the San Francisco Bay while gently swaying on a circular bench —a park-bench/porch-swing hybrid. The perforated steel canopy with its large oculus isolates a radiant view of the skies above. Elmendorf Geurts helped to fix <em>Nautical Swing </em>in 2024. Installed in 2015, created by Matthew Geller</p>

<p>Kyungami Shin/ Shin Gray Studio was selected to create a light artwork for the newly constructed Vietnamese American Social Services Center (VASC). As the first service center of this kind, VASC will service the community with medical, social, and mental health services with bi-lingual services. They worked closely with the architect and the community to create a design that provides an inspiring, harmonious, and healing experience. The main inspiration for the design at the VASC were various rich landscapes of Vietnam including the HA Long Bay (oceans and islands), Terraced Rice Fields of Bac Son Vallery, Mu Cang Chai and North Vietnam. Installed in 2023, created by Shin Gray. </p>

<p>For the South Loop District in Bloomington, MN artist Donald Lipski created a larger-than-life songbird, the American Goldfinch, that can be found perched atop a new sign welcoming all to the South Loop District. The songbird is a nod to the neighboring&nbsp;Minnesota Valley National Wildlife Refuge, home to many migrating birds as well as birdwatchers who travel to see a variety of species, including the American Goldfinch, represented in Lipski’s final sculpture. The songbird also represents other forms of migration and travel via the nearby MSP International Airport as well as immigration which helps to increase and to diversify Bloomington’s population.</p>



<p>With the help of experts at the Refuge, Lipski suggested 10 different songbirds, and the public cast their votes with the American Goldfinch as the winner.</p>

<p>Sound Transit, the Puget Sound Area’s transportation company has expanded their light rail system almost 8 miles, adding three stations. &nbsp;At the station in Federal Way, a town of 100,000 people between Seattle and Tacoma, Lipski created this two-story tall glass desk lamp. &nbsp;He was paying homage to this area, which is the historic center of the contemporary American glass art world. &nbsp;This was largely driven by the life’s work of Dale Chihuly and the glass world he created in his wake. &nbsp; A large lampshade structure consisting of a concrete column and bench, stainless steel internal structure, and glass lampshade. Located in Federal Way, Seattle, Washington, installed in 2025, created by Donald Lipski.</p>

<p>Five hundred eighteen concrete pavers that each contain an array of integral acrylic rods and LEDS, a LED micro controller and a sensor. The sensors triangulate sounds such as footfalls and conversations and create a wave pattern like ripples on a pond. Each sound that is sensed creates a wave origin point and the ripples propagate, interact with each other, and reflect off of the perimeter, all based on the wave equation. Commissioned by the City of Aurora by Milender White for the Parkside at City Center (14531 E Alameda Ave, Aurora, CO, 80012).</p>

<p>720 stainless steel triangles join to create this 8&#8242;, 6v geodesic sphere. At the intersection of each triangle, the surface of the sphere has an addressable LED which allows the controller to create a light pattern across the surface of the piece. In the center of the sphere, visible through the gaps between the triangular panels, is a 4,000 watt LED array projecting the geodesic pattern which can seen on the walls of the venues. The sphere is split into two hemispheres, each is able to rotate independently of the other and the entire assembly rotates as one piece, like a traditional disco ball would.</p>

<p><em>Echo</em> is a site-specific media artwork by Denver artist David Zimmer, commissioned for the exterior of the 16 Chestnut development in downtown Denver. The work brings a moving image of nature into the building’s concrete-and-glass surroundings, transforming a 40-by-30-foot wall into an illuminated, constantly shifting landscape.</p>



<p>The imagery is drawn from three mature oak trees outside Denver that Zimmer filmed intermittently for more than a decade. Their movement in the wind is divided across 13 LED panels and reconstructed as a large-scale digital collage. The title <em>Echo</em> refers to the memories and experiences that have accumulated beneath and around the trees over time.</p>



<p>Each custom screen is built on a 4-by-8-foot sheet of perforated aluminum and contains 3,480 individually addressable RGB LEDs arranged in a hexagonal pattern. The screens sit behind textured glass within painted stainless-steel frames anchored to the exterior wall of the parking garage. Together, the 13 panels contain more than 45,000 LEDs.</p>



<p>The panels operate in six coordinated groups controlled by Raspberry Pi video servers, microcontrollers, pixel controllers, and a distributed power system located inside the garage. The textured glass softens and blends the individual points of light, allowing the moving tree imagery to read as a unified composition from the street.</p>



<p>Elmendorf/Geurts supported the project through structural engineering, electromechanical engineering, fabrication, lighting-system development, installation, and long-term maintenance planning. The completed work combines public art, custom electronics, and architectural integration to create an evolving connection between the natural world and Denver’s urban environment.</p>

As Rose as Rain


<p><em>Leading Lights</em>, created by Catherine Widgery, transforms the K Street underpass in Washington, D.C.’s Golden Triangle District into a changing corridor of color and light. Thirty-four freestanding dichroic-glass and stainless-steel columns line both sides of the street, creating a rhythmic gateway for vehicles and pedestrians moving through the site.</p>



<p>The dichroic glass shifts in color as the viewer moves and as daylight changes. In direct sunlight, the columns project bands of saturated color across the pavement and surrounding surfaces, extending the artwork beyond its physical footprint. From other angles, the glass becomes nearly transparent before reappearing as the light or point of view changes.</p>



<p>Each triangular column is set at a slightly different rotation, allowing its reflective surfaces to respond individually to the sun and surrounding architecture. After dark, solar-powered lights within the caps illuminate the columns from above, turning them into softly colored lanterns.</p>



<p>Elmendorf/Geurts engineered, fabricated, and installed the sculptural system, integrating the stainless-steel structures, dichroic glass, and solar lighting into a durable public artwork. The repeated vertical forms reference the tree-lined boulevards and architectural columns found throughout Washington, D.C., while giving the previously undefined underpass a stronger sense of place.</p>

That Child of Fleeting Time


<p>Fabricated for Brooks+Scarpa, the Gateway Sculpture at Pembroke Pines welcomes guests to a city plaza in South Florida. As part of a new Civic Center Complex that includes a performing arts hall and art gallery for the City of Pembroke Pines, Brooks + Scarpa Architects designed new entry and shade canopy sculptures with attending landscape features. These sculptures and landscape elements frame pedestrian gateways into a new public plaza, providing wayfinding and anchoring a sense-of-arrival. Designed as public art, the aluminum sculptures emerge as tree columns that lead up to an array of rings with perforated plates that spin in the continuous breeze of south Florida. The sculptures provide shaded area for seating, as well as programmable up-lighting that enhances user experience. The pavilion is located in the front of the new Pembroke Pines Civic Center and City Hall.</p>

Portoval


<p><span data-offset-key="di22r-0-0">The <em>Tree of Transformation</em> is the second in a series of 20ft tall interactive musical trees. It takes the form of a twisting steel pipe tree trunk sprouting from a full-size upright piano. Three main limbs branch out to form a canopy and support nine steelpans with a four octave range. When the keys of the piano are pressed, solenoids are actuated to strike the pans in the correct location to play the corresponding note. Because some notes overlap between pans, there are a total of 99 solenoids but only 48 notes, which means that some notes will have multiple pans being struck resulting in a rich, complex sound, much like a steelpan orchestra. As you approach the piece at night, you will only see the piano by way of a piano lamp which illuminates the keyboard, and a piano bench which sits in front of the piano inviting you to play. When a note is played, each striker also has a high intensity white led light that flashes, lighting up the branches and pans in a sequence following the notes being played.</span></p>

Tree of Transformation


<p><em>Robot Resurrection</em> is towering 30 foot tall, human piloted, articulating, fire shooting sculpture made from 90% recycled materials and reclaimed airplane parts. From the torso cockpit, the operator(s) manipulate the Robot’s motions and fire effects. Night time displays include lasers and various lighting effects.</p>



<p>The Robot is a modular structure comprised of the trailer base, legs, torso, arms and head. Each piece is attached to the next with grade 8 steel bolts. It is assembled horizontally and lifted/lowered into vertical position with a winch that is attached to the box truck and then removed. The legs of the Robot are attached to the base with a 6’ long steel hinge.</p>



<p>The Robot has a wireless network with mobile operation to allow participants to control the Robot from the ground, with supervision. All propane lines are custom made from ⅜” stainless steel tubing with flare JCM fittings, with an operating pressure of 30 psi. The two 20 lb. propane bottles are housed in the steel feet of the Robot, each with its own ¼ turn shut off valve.&nbsp;The moving parts of the Robot are 12’ from the ground so they are safely away from audiences. All motion is limited for safety by proximity sensors located in each actuator. Each motion has its own solenoid valve and operates on a 12v fused system. There are 2 separate joystick controllers that control all the arm motions. The head rotates side to side and up and down manually.</p>



<p>Each shoulder has a high torque winch motor to rotate the arms up and down. Just inside each armpit is a pivot point with a pneumatic cylinder to move the arm in and out. The elbows have have linear actuators to move the forearm up and down. The wrists have small motors inside to rotate the hands 180 degrees. All air cylinders run off one 12v compressor and 2 separate air tanks for sufficient air volume of around 25-40 psi per tank.</p>

Robot Resurrection


<p>The <em>Therolin</em> is a revolutionary new type of large scale musical instrument.&nbsp; By pairing a 20 foot long piano string suspended in a steel pipe to a <a href="http://www.thereminworld.com/Article/14232/what-s-a-theremin-" target="_blank" rel="noopener">theremin</a> , the <em>Therolin</em> converts the musical output from the theremin into notes played on the string by &#8220;plucking&#8221; it with electromagnet actuators on specially engineered frets. Traditionally a theremin responds to the hand movements of its player to create electronic sounds, but now <em>Therolin</em> players will use it to play a giant stringed instrument, creating a physical sound in lieu of the traditional synthesized sound.</p>



<p>The <em>Therolin</em> consists of a single 20 foot long piece of 10 inch diameter stainless steel pipe that emerges from the ground at a shallow angle. The end of the pipe is approximately 5&#8242;-6&#8243; off of the ground. As you approach, you will notice that there is a pedestal located near the end of the pipe which has a theramin antenna built in. Looking down the pipe you will see a continuous strand of piano wire along its center line, and a series of supports (or frets) and electromagnetic coils.</p>



<p>A low-profile base plate sits just below the Earth&#8217;s surface, and is anchored to the ground with four screw anchors. This will give the illusion that the pipe is emerging from the ground with no support.</p>



<p><em>Therolin</em> is designed to be minimal and unassuming, while still having an intriguing presence. Participants will be drawn in by its form, and only upon closer inspection will they discover something completely unexpected and wonderful. As they get close to, or reach out to touch the theramin antenna, they will notice a soft musical sound starting to emit. If they move their hand closer to the antenna, the pitch of the sound will rise, and as they move their hand away the pitch will fall. The experience will be the interface of a traditional theramin, but with a more real, physical sound in lieu of the traditional synthesized sound.</p>



<p><em>Therolin</em> is meant to inspire collaboration. Once a participant learns how to play it, they will begin to create impromptu performances and draw in more participants. Based on the artists&#8217; experience with their past works, they anticipate waves of people interacting with it, i.e. once one person discovers how it works they spread the knowledge and excitement to friends and even strangers passing by until a crowd forms, and then eventually dissipates for the whole process to repeat.</p>

<p><span class="_4n-j _fbReactionComponent__eventDetailsContentTags fsl" data-testid="event-permalink-details"><em>Sky Song</em> is a musically interactive artwork on the facade of the newly built Levitt Pavilion Denver. The piece invites you to create your own music and light show by pushing buttons on a polished stainless steel sculpture in the Levitt plaza.&nbsp;&nbsp;</span>Composed of two separate parts, the sculpture is both fixed onto the façade of the pavilion and rises from the plaza at the venue’s ground level. Visitors can press 33 buttons on the ground-level structure to make ethereal music accompanied by glowing light shows above. The structures are mirror-plated, so if you stand at just the right angle during the day, the reflection of the sky creates the illusion that the heavens are reaching through the venue and into its plaza.</p>

<p><strong>Installation History:</strong> Black Rock City, Nevada (2016 and 2023) | When We Were Young Festival, Las Vegas, Nevada (2022) |</p>



<p><strong>Permanently Installed</strong>: Chaos Vineyard, Oregon (2026)</p>



<p>Awakening is a large-scale articulating sculpture and immersive camera obscura exploring the moment we first become aware of ourselves and the world around us. The installation consists of a monumental head facing two hands that rise from the ground. Visitors can climb through the head’s ear to discover a camera obscura hidden inside.</p>



<p>The 16-foot-tall head and hands are positioned as though a giant being is seeing its hands for the first time. Polished stainless-steel spheres form the finger joints, which are animated through a system of aircraft cables and motors. The open steel structure echoes the anatomy of the human hand, with solid plates suggesting skin and the negative spaces tracing the bones beneath.</p>



<p>Inside the head, optical lenses in the eyes project the surrounding landscape upside down across the interior. Colored filters and 3D glasses give the nearly 180-degree image added depth, allowing visitors to experience the world from the perspective of a giant.</p>



<p>Inspired by two of the body’s most extraordinary mechanisms—the eye and the hand—Awakening celebrates our ability to observe the world and create change within it.</p>
