Imaging at a trillion frames per second.

Imaging so fast that it can show light in motion.

What these guys at MIT are doing is pretty interesting. Using a camera that can capture a frame in less than a trillionth of a second, and a little bit of computer processing, they created this video. The video shows a "bullet" of light from a laser pointer fired through a plastic bottle filled with water. The video is slowed down 10 billion times. You can actually see the ripples of light being formed inside the bottle as the light bounces around.

And they have open sourced their data for all DIYers to play around with. That is very cool.
