Yesterday I went to a music and projection show at Espacio Fundacion Electronica. The stage was set up with four layers of curtains in front of each other with the same video projected on all of them at the same time to create a sence of depth on the stage. It seamed like the animations was created real time with a video game controller. The animations was accompanied by electronic music. I would describe the show as two guys playing video games and acting out Star Wars sword fights to music.
To get a better understanding of what it was watch this video.
