Reverse Shadow Theatre is an installation created with Animata digital puppetry software.
Animata is open source real-time animation (or digital puppetry) software that is “designed to create animations, interactive background projections for concerts, theatre and dance performances”. The goal of Animata is to make it really easy to create scenes with digital puppets that can be controlled via physical sensors, microphones or cameras.
Animata has already been used for a couple of interesting projects, including Animata Jazz Pub (an interesting demo that shows how the Animata software can be used to react to live audio input) and Reverse Shadow Theatre (an installation that was created with Animata, inspired by Wayang Kulit, an Indonesian form of shadow puppet theatre).
If you want to try playing around with the software yourself, the Animata software can be downloaded for free for both the Mac and PC. The source is licensed under the GPL and can also be downloaded from Google Code.
