technology
The image is projected to the wall via one or more beamers (backside projection
would be perfect because of shadows).
The area in front of it is scanned from the ceiling by a webcam. The software
analyzes the image if there are changes, and moving piles of pixels are
recognized as persons.
the software was written in processing
with the additional library JMyron/webcamXtra
