Hi Jarod. Basically it's just a really cheap closed circuit TV lens like you get on security cameras. I think it was about $20 it's a bit blurry and everything looks a bit wobbly but it gives you quite an arty effect. You can find them all over ebay and you can get adapters for most cameras with changeable lenses. You can't really use them for anything serious but they're a lot of fun to play around with.
