Camera tossing is all about sending a photo camera up in the air while in long exposure settings to record the whirling moves of the camera into a somewhat different picture. This is an obviously dangerous photo technique (How many times can you strike such a move without letting the camera fall on the floor?) but this is also a way to get out-of-the-ordinary photos.
Wired has an article about this technique. And Flickr allows to search for images resulting from this perillous exercise.
