Lightsource for DIY LCD Projector

xpndsprt asks: "I'm trying to develop my own projector (i've been reading DIYAudio forums for a while and finaly decided to put together my own), but it seems that people are having problems with light source. The Slashdot crowd seems to always have interesting answers to problems at hand, so to get to the point: Does anyone know of a powerful lightsource (200w+) which would produce a high temperature light (5000K+) and would not heat up too much (ppl seem to be using mag.Hylide bulbs, but those seem to heat up tempreture in the room by about 10F. Xenon lights are out of question, since too hot and not bright or white enough. If someone could help, it would be greatly appreciated."

LCD + OHP

[brejc8]

We got loads of these 640x480 lcd screens for £1 each ($1.50). They work really well when they're placed an OHP. Here are some things we did with them. I am currently thinking of placing four of them in a circle and having a powerful light in the middle. Then a simple GAL or FPGA to control it. then have funky colours shining on your wall. Or the time/wather and so on.
Fat boy Matt made a network controled version.
