SPINNING:BODIES was first announced as an interdisciplinary performance blending film, sound art, movement, and live concert. It explored life in a state of crisis, the fragility of identity, 

and language as a final resource. Adapted bicycles—from freak bikes to wheelchair basketball models—become tools for expression, functioning as vehicles, instruments, and performers.

The final performance, which took place on May 17, 2025, transformed these ideas into a live, collective experience.

New concept with enhanced technological element

The event took place in a room styled like an artistic black box, where time seemed to shift with the lighting—gradually dimming until the space was completely dark. The audience was seated not just centrally, but also in the corners of the room, while performances unfolded all around them, creating an immersive, 360-degree experience.

One of the standout moments was a live laser performance by Jerobeam Fenderson and Hansi3D, featuring Cornelia Scheuer and Alexander Suppan. Their act—performed in wheelchairs—explored the theme of escaping reality through movement and motion. For this segment, a laser projector and the zactrack mini system were used to track the performers’ movements with precision. The space, approximately 6 by 12 meters, was equipped with 6 anchors and 4 trackers—two attached to each wheelchair. This way, when the system always received two positions, which were then used to calculate the rotation of the wheelchairs.

Exploring the Power of zactrack

The team had a tight schedule but were committed to using the zactrack system, despite having never worked with it before. With the pressure of getting everything up and running after the first rehearsal, they had to work quickly. The whole team rehearsed for only three weeks.

“From the very beginning, it was clear to us that we wanted to use lasers on the floor, but the details came together later on. What was really important was making sure the performers could be active, creative participants—both visually and acoustically. We wanted to give them the freedom to shape the experience and have real creative leeway," explains Hansi3D.

The result was a powerful blend of technology and expression in an environment that was both intimate and transformative.

We sincerely thank Hansi3D, Conny Zenk and the whole RAD team for their passion and spirit of innovation!
