I built a projector with a ripped apart 15" LCD monitor and overhead projector decades ago, and we could not have been more excited to do some shooter games. We had had a PS2 and light guns all rigged up ready to go, before we noticed the fine print: does not work on projectors, does not work on LCD. And we were running via a tv-input card on a computer. It did not work for us. Delighted to see someone who made it further than we did.
