This High Speed Camera Tracks Light Bouncing Off a Mirror at 100bn FPS

There's also a video of light changing mediums on the YT channel: https://www.youtube.com/channel/UCukPHZgmrDonqpLzUQHr9QQ (I think the video with the mirror is also better on YT.)

The motherboard article is better: http://motherboard.vice.com/read/the-fastest-camera-ever-cre... although I still don't really understand how does this works. Apparently the sensor(s?) moves with the light??

to be clear that is 100,000,000,000 frames per second
