How funny!!!

The site says that for less that $20 you can have a big screen TV... then they go on to charge you $19.97 for the "eBook". I was able to wrestle the heavy duty calculus and differential equations involved, and discovered this leaves me with 3 cents to build the set according to their claim.

This is yet another site showing you how to take a freznel lens and build a CRT projector. It works if done right, but will not give decent results. If it really were this easy, the TV manufacturers would be shipping these sets like crazy!
