Build Your Own LCD Projector

Myself and A.J. have been looking at some pretty cool designs on making a somewhat cheap (Less than $300) but decent LCD Projector. I would be tempted to try (lots of plan white walls to project on in the house). I am going to research it a bit more before pursuing it but it would be quite interesting to watch a movie on an entire wall as opposed to a 27" TV.

Here is the link to a very straightforward description on how to put it all together, including a 20MB video: Tom's Hardware.
