    Cool vid!!! I'm curious, what's making the high pitched sound...what electronic equipment did you use to achieve the effect?

    SUCH a horrible sound! It was a signal generator run through a basic audio amplifier. I used a piece of hardware to generate the signal, but there are programs for your computer that will do the same thing. You just need control over a sine wave to do it.

    Any ridge around the vibrating plate would dampen the vibrations!

    When the frequency surpasses the natural rate of acceleration from gravity, the patterns suffer. Because half of the waveform is being used to counteract the device vibrating on the table.

    Secure the device and the plate firm and the patterns will open up nice!

    Just my opinion, I like this stuff. I see these patterns on American India art.

    Doesn't sound all that bad - I've been to concerts that sounded worse.

    You know when you blow out a candle, and keep blowing the liquid gets a skin in the shape of the disruption during cooling.

    In-vision a bath of candle wax, vibrating resonating, and then very sudden being cooled down, holding the shape.
