Ripple Matrix

This is a recent interactive artwork I'm just getting around to documenting. I showed it at the "TV of Tomorrow" conference in April.

This work is a 8 x 15 array of full-color LEDs, driven by an embedded Linux board. Each LED is addressable, and optical sensors make the work interactive if you touch it. I'm running a digital simulation of the 2-dimensional wave equation. Think of water in the bathtub: it's quiescent when not disturbed. However triggering an optical sensor does the digital equivalent of throwing a rock in a pool: it disturbs the initial conditions, and sends ripples propagating away.
