Tools of the Trade

So far I've some basic components gathered:

* A DLP projector.
* Two sheets of 11"x14" acrylic (thanks Home Depot!)
* 4 flat-head screws & bolts (#8-32 x 3/8") for holding the acrylic together.
* Drill & bit. (Drill da holes in the acrylic)
* Webcam (You getting all of this?)
* Velum sheet(s) (thanks Martha Stewart!)
* 4 IR LED's, 16mW min. 940nm, 45 degrees (enlighten me.)

Of note: acrylic is fragile.. drill holes into it sloooowly.
