Through a process of foreground subtraction, the project removes people from a space which otherwise would be difficult to capture empty. Using either time-lapse sequences, movie scenes, or live video as the content, users are able to watch as the people begin to fade away and the background is reconstructed. The video below shows the image as it is being processed.

Exhibited in 
Geekdown at 92YTribeca. Some press on the event is available from DNAInfo.
