"Ricochet” (bounce) materializes wavelengths and sound variations diffused by the high, medium and bass speakers. This speaker family takes advantage of the sound vibrations and projects images corresponding to the noise intensity. The music becomes echoing pictures reflected around the inside space such as wall and ceiling. A thin surface of water “twangs” above a chromed reflector, the water vibrates like a membrane depending on the noise and wavelengths intensities – high bounce, medium bounce, bass bounce - of any music, thus a composition of caustics is projected, accentuated by LEDs light emission. "Ricochet" speakers insur a 360° degrees sounds and caustic effects. This project will be exposed as art gallery installation in 2009. The name of the gallery will be know soon at Yatzer.
