Sci-Fi Happens and Lasers Go to School

The idea of having a laser as a projector light source instead of a lamp still seems sort of sci-fi to me. Rather like something you expect to find in some advanced research lab or or the rebel alliance in a galaxy far, far away. I am still waiting on my light saber, but I don't have to wait anymore for a laser powered projector.  Better still, you can get one too, right here on earth.  They are bright, affordable and very effecient.  There are lots of great uses for a laser based data projector - especially the classroom.
