Guillaume Reymond and his collaborators at NOTsoNOISY created this amazing stop-motion video of space invaders. Sixty-seven people act as the "pixels." The three minute video took 4 hours to film. It was a project for the festival Belluard Bollwerk International earlier this month in Fribourg, Switzerland. Last year, the group produced a similar piece based on Pong.
