The Slowest Slo-Mo Ever Recorded

Image credit: 

"How does light look in slow motion?" asks Ramesh Raskar in this brief TED Talk, demonstrating his "femto-photography," a slow motion technique that achieves one trillion frames per second. He proceeds to show us: the camera captures so many frames that you can SEE LIGHT TRAVELING THROUGH WATER. You can see light moving across the surface of a tomato. It's frickin' insane.

Oh, by the way, this technology can also see around corners. It's not perfect but, you guys, it took me like a whole afternoon to make my periscope, and now I just feel like a chump.

He's serious about the open source bit, though it's mainly video and papers: check out the CORNAR website for a bunch more information.
