I think the camera toss phenomenon, started by Ryan Gallagher (also see his Flickr stream), is really cool. The idea is that you set your camera for a relatively long exposure in a dark place with a nifty arrangement of lights, and throw the camera in the air while the shutter is open. The results can be jaw-dropping.
I decided to give it a go while I was out shooting pinholes the other day. At f/235, I figured I’d better do it outdoors in bright sun to have any chance of getting anything on film. As it turns out, the sun was the only thing that actually turned up. This is on Fuji Astia 100F cross-processed in C-41, shot at about ISO 25, with multiple tosses in the air per exposure.
I may use this one for holiday cards this year (if I send any), as I think it looks a bit like a wrapped present:
