My friend Pubert created some videos over the last few months using an incredibly awesome camera which I believe is called an EX-1. It shoots up to 1200 frames per second. When played back at normal speeds, those 1200 frames add up to a incredible video ride, even for innocuous seeming water with food coloring.
