    A fascinating visual representation of the science of sound. Thanks for the share!

    Actually, that IS normal FPS (at least here). 25 FPS.

    If you have a sine going 50Hz, well, you get the "non-spinning wheel on a car". Going lower, you get the "wheel on car going backwards while driving forward". No magic, just plain math.

    So the title should be "Hertz vs. frame-rate = optical illusion".

    Man I got to try this *yes*
    it is played at normal speed, but they use fixed frame rates to get to this visual representation, which is all explained right here Nigel Stanford Cymatics

    I know, right?! American fluoride tap water. Better with non-fluoride water. :wink:

    I'm glad I live in a place where they don't put that shit into the the water.


    Speaking of frame-rate and optical illusion, you know you can reverse the initial way this train is moving (if you really try to):
