This is a crack-up! These "kits" have been around on ebay for years. It's basically a set of instructions and a fractal lense.
I bought a couple of these things a few years ago out of curiosity and to compare the two. You have to build a projection box to attach to the front of your tv. Oh, and I almost forgot to mention, you have to turn your tv upside down in order to see the picture right side up. Yeah, and most television sets today get screwed up when they are turned upside down. The picture becomes distorted and the colors go crazy.
It's not easy to get a good, well-focused picture using this method either. Basically, you pay these guys $16.95 for 50 cents worth of stuff and then spend forever trying to get it to work. It's not worth the time or effort unless you really like do it yourself projects. Save up $2,000 and get a decent Mitsubishi rear projection tv...or, save up $60,000 and buy a nice Runco projector and get it professionally set up. You'll be much happier with the results.
