I was sent a brochure on this thing a while ago, but tossed it. It's an
LED overhead projection unit with a little attachment on it. The LED
unit projects the Mac screen on the wall, and the attachment senses the
motion of a laser pointer on the screen. It also senses when a little
button on the laser pointer is pressed. So, in effect, your laser
pointer is a mouse, moving around on a projected image of the Mac
screen. When you point at menu title and click the button, the menu
opens up. Just like a mouse.

It sounds really cool, if it lives up the claims in the brochure.
