So what I am looking for is a projector, that hangs on the ceiling or whatever, see's what is on the desk below it, and projects that to the wall. Does this make any sense? If not I can give more details, but I'm not really sure how to word it lol! Anyone know of something like this?

It sounds like you want an overhead projector, like they used in school, but with actual color images instead of a light through a transparency?

Exactly, and one big enough that it could show like blueprints and stuff. Is there anything like that out there?

I think the main reason it hasn't been done is you need light to focus onto the wall. The schoolroom overhead projectors had the bright light at the bottom shining up, through the transparency. I don't know how you would get sufficient light unless you had a bright light shining down and everything on the desktop was reflective.

Maybe some time of Webcam addon thing would be the best chance.

'Webcam addon thing' yeah second that. Video camera > pc > projector.

Although most OHP's work on transparencies, you can get ones that work on reflected light - for books etc. I used to work as a technician in a college years ago, and once borrowed the 2nd type to draw a giant mural of some Marvel superheros on my flat wall. My mates would say 'hey - I didn't know you could draw' . . .
