<Illusion>is a multi media installation integrating percussion instruments, interactive video projection, and EEG signals.
The 8 modules of instruments are lying in a semi-circle. Each module creates a vertical motion like a seesaw and consists of few weights. The weights strike 8 different materials such as skin, iron, wood and glass. The rhythm and timbre are determined by 1 dimensional cellular automata algorithm. There is a listening chair in the center of the semi-circle which is facing a screen with an extreme close up shot of an eye image. The whole system is controlled by Alpha brain waves which emerge with the closing eyes.
