The animation you see on this building isn't computer generated. Instead, it's done with human hands. There are people inside each room as they shut each window to create a building wall that look like pixels moving about.

The performance done by HESAV (Health high School Vaud), in this 11-story building, was created by NOTsoNOISY Guillaume Reymond and Trivial Mass Production. Check it out after the jump!
