I own a Canon Powershot sd450, and last week I stumbled with this piece of software called CHDK that hacks the firmware of Canon's Digic II based cameras, allowing for great stuff like super high speed pictures, motion and light triggered photos, RAW pictures, etc.
The next three pictures were taken with my sd450 with CHDK loaded at 1/10000 of a second. It was very tricky to be able to take them as the sd450, that is a point a shoot camera, does not have a flash intensity regulator, so I had to regulate it with tape and cotton. I had to take over 100 pics to be able to come with this.
