iPod Shuffle Spy Camera
Believe it or not this is a spy cam. Yup, it looks just like the recently released iPod Shuffle, so it should have no problems fitting it. To the right of the controls is a pinhole that contains a small camera that can capture 640×480 video. Unlike the actual Apple device this one contains an SD card slot and can play your favorite MP3s while you record all sorts of nefarious activities. The only downside is that the battery will last for just one hour when in full operation.
Brickhouse has it for $100.
