Webcams are a dime a dozen, and if you can think of a topic, it is likely that already exists. For fans of Spiderman, is this cool webcam. It is an official Marvel and gives a lot of geek references. Peter specifically put your camera in a webbed sticky mess so you can take pictures of him in the locker room. Even a small film that has come out of the side of the camera showing some shots.
The camera itself is nothing special, just a USB webcam. Have a good base and a 4-foot USB cable that will give you much space to the position of the cam properly.
