This is a photography picture that might sound absurd, but gives amazing results. You pretty much go in a dark room and put some type of light infront of the camera, then toss and spin the camera with a 0.5-1second shutter.
Google "Camera Tossing" for more information.
In this case, I used this image as light:[link]
Slightly edited brightness in Photoshop since my aperture wouldn't go any lower. It's 90% non-edited though.
