This crazy amazing video from Bot and Dolly shows two robotic arms spinning and twirling screens in a demonstration of a 3D projection mapping system that makes it appear as if magic was happening in front of your eyes. Everything you see in this video is a projection, and recorded live in their studio, with no post-production editing. 

The robots' movements were controlled to a tee, and the camera which recorded this video was probably controlled by a robot as well. The video ends with an Arthur C. Clarke quote that fits very well: "Any sufficiently advanced technology is indistinguishable from magic."
