Lomography, which is a maker of toy cameras, has this really cool camera called the Spinner 360. It creates true 360 degree images on regular 35 mm film.
It's described like this on their website:
Go beyond the confines of standard panoramas with the Lomography Spinner 360°! Just hold the camera in one hand, pull the cord with the other and release it. In one split second, the camera spins 360 degrees on its own axis, capturing every detail around you on 35mm film - The result is a super-wide angle image, 4x longer than a standard landscape photo!
Someday I'm getting one of these cameras.
