my acid-freak freshman year roomate at 'Bama did this with his 19" viewsonic about three years ago. the lens came from a really old, really large overhead projector, and the hood he made from a u-haul wardrobe box(y'know, the telescoping kind?). Focal length was kinda tricky, as I remember, and brightness was _REALLY_ low, but image clarity was excellent. Kipp had rigged a fractint slideshow so that it was timed to a winamp playlist. effect of a 15 foot screen was impressive (at least while you were on the psychedelics)...
