you will need:
1. a film or video to display
2. a projector
3. a lot of naked people.
paint your naked people white or yellow.
have them lined up as closely as possible. train them for various movements if you like as long as they stay close. if your projection is long you will want enough naked people to rotate them out in rounds, as in, one person leaves as another person joins. this could go on indefinitely.
project the film or video on their bodies.
this is an installation.
