Übergeek Dungeons and Dragons Setup

Check out this übergeek gaming table using an LCD projector mounted overhead to display the current game map. He uses Photoshop with the eraser tool to hide and show the map, which is pretty ingenious, since you could interactively add pretty much anything you'd want to add with very little trouble. If you use an extended display instead of mirroring the displays, your mac could display the player's view on one screen, and all your DM notes on the laptop screen, which would be ideal.
