I have just made a kinda DIY Projection panel, to use wiv my OHP out of a 2.2" Casio LCD Pocket TV, the image is very pixelated but i am impressed for a screen that size, the best size i got was 35" without it going blurry. I have bought a psx LCD of ebay and i hope to do a similar thing wiv that. i will upload pics of the casio and psx (once i get it going). great fun to muck about wiv. after this i will probably take my OHP to bits and make the whole thing way smaller.
