Bloom — a struck resonant surface
Strike a real material and hear it ring with genuine non-linear physics: hit harder and the pitch blooms sharp then glides home, energy sloshing between its modes into an evolving shimmer — while you watch the vibration draw itself as a living Chladni nodal figure.
Sound on. Press start — a seeded autopilot begins striking the surface; your first touch takes over.

Surface
On the surface: horizontal position sets the pitch (left low, right high, continuous — never snapped to a scale); vertical position sets how hard you strike (top = hard and bright, bottom = soft). Drag to scrub. The picture is the sound — bright violet filaments are the nodal lines where the sand would settle.
