24fps camera and a 24hz sine wave. Crazy effect

This is a crazy effect that you see from the camera, not by the naked eye unless you use a strobe light. With your eyes you just see a "messy spray of water".
Kind of similar to the plane prop effect you sometimes see on film.

Makes me question reality.

Awesome!

I wonder if you could find the rate at which our brain processes motion by adjusting the hz until you could see the same effect with your eyes...?

edit: http://en.wikipedia.org/wiki/Frame_rate
10ms frame rate which is roughly 10-12 fps. Wow, we are slow. But there's a lot more going on in our image processing. hmm.

I've observed a similar effect with fluorescent lighting and certain high frame rates in action shots stretched out in slow motion.
