dulcimer

One plucked string and the box it sounds over, simulated as two coupled wave equations — a stiff damped string, and 3D acoustics around a rigid body — both written as the MATLAB below, run in your browser by numbl and compiled to WebGPU compute shaders. Pluck it, watch the sound, put a microphone in the air, and listen.
