Last March we did a residence with Organic Orchetra, with the objective to build and create prototype of projects. With Roni Sax and Cyril and Ben Kuper we developed an idea that we are now looking to build. The concept would be to create a roof made of triangle's structure, were the joins are movables with motors. This would allow us to change the shape of the roof using the Leap Motion, as it was a Marionnette. We would also detect in real-time the position of each triangle to be able to project map on them animations related to the music that would play. We could also use some music descriptors, like music emotions, in order to have a movement behaviour that would be related to the music emotion. This is the video explanation of the project...beware its in french !
