I appreciate the tips!
You're talking about how a projector throws out a trapezoid instead of a rectangle if it's above or below the screen, right? I didn't know that would impact the picture quality - I understood that you could adjust the shape of the image.
My reading suggests that a DLP projector is probably brighter than an LCD, so I'm thinking I should go with DLP. LASER sounds good but too expensive.
I have a WII, and you're on a good track, that would be fun as heck.
