If you cross your eyes, this picture pops into 3D! Click on the picture above to get to this Flickr MAKE: Strobe Photography group photograph for more instructions if you have trouble seeing the 3D picture.

Here is how it works:
High-speed pictures are taken in the dark, and sound triggers the flash. The camera is set to a long exposure time, but since the room is dark, the only light available is from the flash. If there is more than one camera, both cameras use the light from the same flash. In this picture, two cameras at slightly different angles share the light from a single flash, and capture the moment in 3D!
