Instant Replay

This week, we are playing Hockey.  I wanted to use a game clock, so students would know when they would get to sub in.  I set the online clock for 2 minute games.  Using my wireless mouse I can start and stop the clock from anywhere in the gym.

I used my projector in rear projection mode and projected the clock on the screen.

Then I decided to add a 8 second delay of live video for a replay camera.

After that I added a hockey goal horn sound affect(bottom left).

I can control everything from the wireless mouse in my hand.
