I wrote about The Ripple on NWN a while back. In that post I said
Douglas Story and Desdemona Enfield, the creators of DynaFleur and Storm Eye, have put their creative minds together to bring us another fantastic build called The Ripple, a Meditation on Waves. The soundscape for the work was created by Emily Wilkins. This kinetic, interactive build is composed of approximately 600 prims arranged in an architectural fashion, which display video that changes in a fluid, rippling way in response to the visitor's touch. The movement of the prims is accompanied by a wave of audio. I explored the work alone and loved it but I imagine it would be great fun when enjoyed by groups of people, all interacting with the art simultaneously.
It is really a beautiful installation. Check it out here.
