Body Chimes
Your moving body plays an invisible, room-sized instrument of struck resonant bodies. Each limb rings the bars, bowls and bells it sweeps through; the room slowly accretes into a shimmering cloud.

Design notes — Body Chimes / Struck Room
The room suspends 24 resonant bodies — bars, bowls and bells — in a dark 3D volume, each tuned to a just-intonation degree over a low ~110 Hz root so the field is always consonant. Your wrists, ankles and head become luminous strikers. When a striker sweeps through a body with real speed, it strikes it: the body rings and visibly blooms, and its amplitude is set by the limb's velocity. A per-body refractory window stops machine-gunning.
Each ring is genuine modal synthesis: a bank of high-Q bandpass resonators excited by a short impulse, one resonator per physical mode. The partials are inharmonic and characteristic of the body — bells ~[1, 2.0, 2.4, 3.0, 4.5, 5.33], free-free bars ~[1, 2.76, 5.40, 8.93, 13.34], singing bowls nearly harmonic ~[1, 2.01, 2.83, 4.22, 5.0]. Higher modes are excited less and decay faster, as in a real struck metal body.
Long-form accretion: every strike feeds a sympathetic mode-bed — always-on resonators tuned to the scale that linger for ~25 s and slowly grow over ~4 minutes, biased by a struck-body memory and a ±0.35% root detune that breathes on a 90-second cycle. Minute 5 sounds fuller and subtly shifted from minute 1. The central warm light brightens with the cloud.

Controls: press Start, then move. Camera denied or MediaPipe unavailable → a ghost body drifts through the field so the piece plays hands-free.
