An instructables member, MattBothell shares his amazing work of constructing an iPod/iPhone Projector that according to him, has good enough quality to enjoy a full length movie from your iPod Touch or iPhone.
With his step-by-step design tutorial you can actually build yourself a projector with just a few cheap objects and ingenuity! The whole project only cost you a dollar. The way it works is the light from your phone or iPod goes through the magnifying glass and magnifies onto the wall. The whole project is very easy to make and easy to understand.
