Watching Light Travel

If you thought this was fast...

Professor Ramesh Raskar of MIT has been taking video at a trillion frames per second. (Normal video is 30 fps.) The video from his camera of the bullet passing through the picture above would take a year to watch...just fast enough to see light travel. It turns out that if you can watch light travel, you can see the ripeness of fruit, see around corners and observe relativity.
