This is one of the projects I wish I had done, uniting the capturing of a space and the projection back into the same space using motion (camera+projector rotating at same speed).
The camera is mounted in the middle of the room on a turntable, recording the space and the actions in it (top image). Then the whole space is spraypainted white (middle image). Finally the recorded film/video is projected back into the space, projector mounted on the same turntable as the camera was (bottom image).
The first version was done with film in 1980-84, then made for digital video in 2005.
Naimark has written two very interesting papers relating to this work, and you can also find two videoclips from the installation, one from the film version and one from the digital video version, on his website.
