It's just a fresnel lens that you place inside a box and attach to a display device. Just for kicks, I bought one of these off Ebay a couple of years ago for about $8 and it was worthless.
Originally posted by amrod my friend bought one and we tried to build it (from ebay) and the TV had to be like 1' away from the wall in a dark room and it was super fuzzy, it was a good waste of a afternoon. The TV also has to be upside down and brightness turned up to the max |
