be extremely careful about lighting (Score 3, Informative)

A note to the author or anyone else considering a front projector for home theater: be very very wary of lighting conditions. If you have, say, a dedicated home theater in a basement room with no windows, or any other type of situation where you can completely control your environment, front projectors may very well be the best option (man, that adjustable screen is cool!). But any sort of ambient light at all is going to make you extremely unhappy with the picture. Home theater projectors are far different from computer-based video projectors in this sense. DLP is as bright as front projectors come, and it's still not good at all in a room with ambient light. And I'm not just a videophile being picky. Go to an Ultimate Electronics or if you're lucky enough to have a Magnolia around, go there, and demo one out, asking the sales rep for a small amount of light in the room. Decide for yourself. These things aren't for living rooms, or any room with a window, or somewhere where the next room over will frequently have a light on, etc... But that being said, in a completely controlled environment, front projectors rock. And the engineer in original post should build his own, to satisfy his own curiosity and because that's just damn cool.
