Although it's not my original idea (far from it), I finally decided to tear apart my LCD monitor and give this one a go. I had to innovate a few parts, so I hope my solutions help anyone out who's attempting this awesome project. This is my first instructable, be gentle :)

Signing UpStep 1: Materials and Initial Disassembly
Materials:
LCD Monitor, any old one will do, the backlighting is going to be ripped out anyway. In my case, 14" was perfect, larger would have gone outside the border of the overhead's window.
Overhead projector, like from school. I'm no expert at these, and living in Taiwan, it was nearly impossible to find, but I know there are loads on ebay for cheap.
Document protector, used for housing the power and settings strip of the monitor.
Cork. Self explanatory.
First, get the LCD glass out of the monitor by carefully unscrewing, dismembering and prying. Be careful around the wires and you should be fine. One handy thing is that on mine, the display cable was detachable from the motherboard, so that made it easier. It's helpful to have a second pair of hands for this, in my case, I used my girlfriend's.

on the projection screen using two projectors projecting the same image simultaneously, using a splitter for the videocord projecting the same image) will improve picture brightness/quality. just a thought. probably going to try that myself when i get money.
Also i've tried with a cheapo tv and gotten murky semi watchable images, it helps the picture brightness to have the room completely light tight , even if its dark out (starlight/moonlight/streetlights will cause problems because the picture is faint) cover windows
with a blanket, cover all led's in the room.
,and the price for the lamp is minimum $2000
awesome work!
I've taken some pointers, and made my own.
Did you have a problem with the LCD being too big for the projector? - I can't project about 10% of the screen - which is where the start bar is on one side, and the quicklaunch bar on the other side is. how did you fix this?
Cheers
they're a fraction of the price (if they cost anything at all) of a data projector which plugs into a computer and can project moving images
and I got an LCD monitor from the IT department because the backlight didn't work - perfect!
= one data projector ASOLUTELY free
The further you move the projector away from the wall, the larger the image will be. So if you have a really long room, you canmake the image huge!
The only limitation is the power of the light in the projector compared to the ambient light.
Therefore, the darker the room, the further back you can move the projector and the larger the image you can have.
With a pitch black room, the image can be pretty darn big.
The difference is that it has no screen, and has no input for a video device (or any capability of such.)
They are pretty much old technology, i just finished High School and they dont use them anymore, but they did when I was in primary school!
they should be pretty cheap nowadays!
