According to co-director Alan Poon, the video was made using an "experimental 3D scanning technology that detects the displacement of a grid pattern of any object in front of it. ... The data is then used to rebuild the object in three dimensions. Each band member’s performance was scanned using this technique and manipulated in the computer to create the effect you see in the final video." Got it.
