We describe the interactive demonstration 'Instant Replay' to be shown at the Emerging Technologies at Siggraph 2006. Instant Replay is an example application of an inexpensive, highly accurate 'motion capture' system that is able to effectively track many fast-moving, rotating objects. The system works at very high frame rates (500Hz), and reduces cost by employing relatively simple LED projector components in place of high-speed cameras. The cost of the system is only a few hundred dollars.
