build-up of stills

There would be a still camera set up facing the performer, perhaps from an angle other than the front. There would be a projection onto a back screen from a computer. The performer would carry some sort of wireless trigger, perhaps a presentation clicker, or perhaps a receiver that could pick up audio cues? Something discreet (or not). When activated, the transmitter would cause the computer to take a snapshot of the action onstage, then to display the image, layer by layer, on the screen. Think *skate magazine ad*.













How would the layering work? Consecutively might be added on top (or behind). There might be a way to tell which snapshots of the performer are from a greater distance - then to layer the in that order. The relative positions of the performer in the snapshots would have a lot to do with the final image. The formation of the image would be a story of its own. In the picture, there is a presence of the performer's former selves.

Would a blue screen be required? The new iChat, coming with Leopard, uses some technology where a picture of the backdrop is taken, then this is somehow subtracted from the moving image being captured. This would be even easier with still photography.
