All Things End was inspired by CTD senior Kaitlyn Callaway’s love for music and its impact on human emotion. The immersive experience tells a story of human emotion through music and audio reactive visuals projected around an audience. This show is designed to evoke emotion and challenge perspective, with the idea that each person will resonate differently.

“It is the culmination of personal experience, musical production, creative design, and technology,” Callaway said. “It is the embodiment of my style, music, art, and soul.”��

All Things End is one of several music-focused projects Callaway has produced in her four years as a CTD student, including a prosthetic device to help people learn to play piano.

“CTD has been so impactful for me,” she said. “This program has not only taught me technical and engineering skills but also influenced me to use those skills to create what makes me passionate. I would not be the engineer and creator that I am today without the support and structure that CTD facilitates.��

Echo comes to life through a blind-box series of four collectible figurines, each tied to a different instrument and part of an original song. An animated short and interactive speaker invites viewers to mix the music themselves by placing each figure into its slot, alongside a large-scale character table.

CTD senior Jeb Davis (they/them) asks users to step into their personal struggle with anxiety and depression through a 3D puzzle game called "A Heavy Heart".��

“The main in-game driver for this is a device strapped to the player's chest that's powered by a black hole,” Davis explained. “This device comes from a more personal inspiration; I generally describe the physical feeling of anxiety and depression as this inward pull in my chest, almost like a black hole. It acts as the ‘tangible’ metaphor for mental health, but it's also the main driver for evolving gameplay, story, and environment, acting as a metaphor for how a mental health struggle affects the self.”

Davis took cues from the first-person puzzle-platform video game series Portal for A Heavy Heart, paying homage to the former series’ minimalist aesthetic and narrative-driven experience.����

“What draws me to game design is the vast possibility of experiences through agency and interaction,” Davis said. “I've felt the possibility of what you could experience through games for the longest time, but I hadn't really pinpointed what made games different from other art. It's only more recently that I've been able to recognize that there's something unique and special in the interaction of games that makes them art in their own right. With A Heavy Heart, I've only scratched the surface of exploring what I can do with game design, and I'm excited to keep exploring what else I can do with it in the future.”

Riem, by CTD master’s student Sylvia Robles, is an interactive art installation that lets visitors control lighting to explore how shadows transform through stereographic projection. The projection is inspired by the Riemann Sphere, a mathematical model that represents all complex numbers plus infinity—and if that seems complicated, don’t worry.

“I've always viewed mathematics as the language we use to understand and model the natural world around us, whether through numbers, equations describing speed and distance, or patterns in nature,” Robles said. “What excites me most is discovering mathematical applications in places people wouldn't normally expect—art, natural phenomena, even magic tricks. The moment I learned about stereographic projection, I saw its potential to create beautiful art. These sculptures, built on mathematical principles, surprise and challenge people's perceptions with their unexpected shadows.”

Robles built custom-designed sculptures and paired them with motorized lighting systems that allow people to manipulate projections in real time, showing how geometric properties change as light moves. She hopes the exhibition makes abstract mathematical concepts tangible and engaging for general audiences.

“Even though I'd always been a creator, I didn't have the computational fabrication skills to bring Riem to life before coming to ATLAS,” Robles said. “CTD gave me the technical skills to fully realize the creative ideas I'd been developing since my undergraduate math degree.”

For the many climbers in Colorado, RotoClimb could be a high-demand training tool of the not-too-distant future. The motorized prototype allows hand and foot holds to rotate, turning traditional board climbing into a more interactive and creative experience. Tackling a 5.10 climb like it's nothing? RotoClimb could shift the jugs, slopers, pinches, pockets, crimps, edges, and underclings in a matter of moments to present you with a more challenging 5.11.��

Yoder’s concept further innovates on existing training boards like Kilter and Tension.��

“RotoClimb brings my passion for climbing into my senior capstone project,” says creator Joe Yoder. “I believe passion-driven work creates the best results, especially in a radically creative program such as CTD.”��

The Sopris Board is a modular snowboard with swappable tails, allowing the rider to adjust from morning powder to afternoon park laps. It was built out of “frustration with overpriced snowboards, gear clutter, and a desire to introduce modularity into an otherwise stagnant sport,” says co-creator Ellyse Jensen, a senior in CTD. Project collaborator and fellow snow sports enthusiast Aiden Youell—also a senior in CTD, with a minor in computer science—handled construction research while Jensen focused on the modeling and technical aspects, coming together for the actual fabrication.��

Named after Mount Sopris in Colorado's Elk Mountains, Jensen says the board’s name reflects the creative duo’s design philosophy.

“Mount Sopris began as a single underground formation, later shaped by time and natural forces into two distinct peaks, each with its own character,” she explained. “Our snowboard follows a similar concept: a unified core paired with interchangeable tails that transform its performance. The name also serves as a tribute to Colorado, where the board was designed, built, and tested.”

The Sunnyside Scrambler is the CU �鶹ӰԺ Theme Park Engineering and Design (TPED) Club’s second entry into the national��. This competition asks teams of engineering students across the country to create a theme park ride intended for candy riders (i.e., literal sweets) while adhering to real-world safety standards. The Sunnyside Scrambler adds a kick to the traditional scrambler setup (cars on two separate axes creating intense centrifugal force) by placing the cars atop a moving scissor lift.��

“When designing the ride, we started with the ride type, a scrambler, and from there we threw around different themes but loved the idea of doing a play on words,” said CU TPED member and CTD sophomore Erin Fels. “Finally, our goals of scoring well in categories like safety and mechanical design led to the full design of the Sunnyside Scrambler. We couldn't be happier how the final product turned out and were so excited to see the ride vision come to life."��

The Sunnyside Scrambler was designed and documented in adherence with professional ride design standards, including ASTM F2291. The team placed second in the west division out of 16 teams at the Ride Engineering Competition.
