Using the BBC’s Big Screens, which are installed in various UK city centres, the Hand From Above playfully transforms passers-by. “Unsuspecting pedestrians will be tickled, stretched, flicked or removed entirely in real-time by a giant deity.”

“The BBC Big Screen is fitted with a CCTV camera, linked into a computer that runs the software then outputs to the screen. The software picks a person based on their proportions and how apart they are from other people, then tracks the blob over time using optical flow.
