For those of you with projectors, I was wondering of one of you could conduct a simple experiment for me. Its quite simple really. I would do it myself, my projector is almost done, but I'm too impatent. lol. I'm dying to know. I thought maybe one of you would be willing to find this out.

Project onto a wall, perpindicular to the screen, that is with zero keystone correction. Just a straight forward projection, perpendicular to the screen, and then tilt the collector as if you were doing keystone correction. What happens? Does it produce a focused trapazoid? Or does it produce an out of focus trapazoid?
