Talk about immersive art.

Multimedia artist Ryoji Ikeda on Tuesday presented to visitors - or rather participants - to the Confluence museum in Lyon, France, an artwork called Supercodex, into which they could walk.

The Japanese artist is a leading electronic composer and visual artist. Born in 1966 in Japan and currently living in Paris, Ikeda has gained a reputation as one of the few international artists working convincingly across both visual and sonic media. He elaborately orchestrates sound, visuals, materials, physical phenomena and mathematical notions into immersive live performances and installations.

All of which simply means that during his performance, he may have turned the Lyon museum into one of France's hippest clubs.
