"Intro Act" is an interactive computer installation, which was developed by Sommerer & Mignonneau for the 95 Biennale de Lyon and in is now in the permanent collection of the Musee d'Art Contemporain in Lyon France.

In "Intro Act" visitors enter the installation space and immediately will find themselves projected into a virtual space in front of them.

As they move their body in the real space, different three dimensional evolution of abstract organic forms will be synchronized and linked to the visitors movement and gestures. Like exploring a different universe, the visitor will try to orient himself, finding out which movement will cause which event. Lifting for example his arm, will suddenly lead to extensive development of wild growth explosions out of his hand.

Other behavior and movement will lead to destruction of organic forms, whereas other gestures will lead to construction, expansion and differentiation of the virtual species. The visitor becomes totally engulfed by this virtual world, the longer he or she interacts, the more he or she will be part of the system. The visitor continuously sees himself inside this three dimensional world, he defines it, creates it, destroys it and explores it.

"Intro Act" represents a universe of unexplored abstract organic forms that react and interact with human beings.
