An experimental VR composition with geometric model of torus (closed moebius strip) and acoustic model known as Shepard tone (infinitely ascending or descending tone). The foot mounted interface (a.k.a. Cyberboots) transforms the torus and the sound synthesis algorithm. This way, three-way circularity is enabled: walking pattern (kinesthestic orientation), torus rotation (visual orientation), and algorithmic rotational shifting in the sound model (acoustic orientation). The analogy anchors in the poetics of infinity. Torus model by George Francis. Cyberboots by Insook choi and Carlos Ricci.
