The HypnosEye turns your iPhone or iPod touch into a projector. No external power source is needed. The HypnosEye uses only the light from the iPhone screen, so it does require a dark environment. The HypnosEye works with photos or videos. The projected image size is 17″ to 45″ from a distance of 0.5 to 2 meters. There is a 19.75″ X 27.5″ screen included in this kit. They do warn that the projected pictures are likely to be fuzzy at the edges. The HypnosEye is available from Jzool.com for $109.80. YouTube has a video showing how the HypnosEye works.

So it’s basically just a giant magnifying glass thingy? Why not just spend a little more and get a real handheld projector? They work with iPhones. I bought this one from Aaxa and it has been great. http://www.aaxatech.com/products/p2_pico_projector.htm
I mean how much light can the iPhone itself actually give, and what happens when the iPhone goes into standby mode and turns the screen off?
