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.



i really love this project, it is similar to one i want to create for a light installation with a slightly different purpose.

i was wondering if i could get some advice about how to do this.

i am pretty much a beginner but i learn quickly and determined to make this work.

my email is twentyfourseven_mh (a)

i really hope you can help if you have a bit of time.

thank you so much,

kind regards
