Resonance Room · Sand & Sound
Explore the geometry of sound: sweep frequencies, step through square-plate and drumhead modes, alter size and superposition, scatter real simulated grains and watch them gather near nodal lines. Sand, standing-wave and combined views; optional locally synthesized sine tone, keyboard mode controls, pause and resting-grain status. Open-ended interactive studio, not a scored game. Original particle dynamics, Bessel functions, mode formulas and procedural Canvas graphics preserved. Modal formulas are illustrative approximations, not a calibrated mechanical solver.

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
