Have you seen Jerobeam Fenderson?
Apart from having one of the best names of all time he also produces this incredible audio visual experience.
Does anyone out there understand how the pictures can correspond to the sound? I am mesmerised, but I can't work out how the two relate. There doesn't seem to be a relationship between position or movement of the light and the sound.
Whichever way, he is making some great music and lovely pictures, but is it really what he says it is? I want to trust the guy, but the things he does look like magic.

Almost nothing by the looks of it.
But it's not like the representation of sound is moving right to left, like a heart beat monitor, is it?
Are we effectively falling into the sound, so that at each instant we 'see' the noise, but not what's coming towards us because we only see one slice at a time?
And what do the x and y axes represent? Are they volume and pitch?
Answering in the reverse order for clarity. As far as I can tell, the axes both represent amplitude of the wave – essentially volume. The audio has two channels, left and right; the x-axis...

As far as I can tell, the axes both represent amplitude of the wave – essentially volume. The audio has two channels, left and right; the x-axis represents the amplitude of the left audio channel, and the y-axis the same for the right channel.

I think so, if I understand what you mean. A sound wave might look something like this (x-axis time, y-axis displacement); that's the type of wave being played on the left channel at 22 seconds into How To Draw Mushrooms On An Oscilloscope With Sound. As time progresses, the displacement of the image changes. The sound being played there is at a very low pitch (the wave is quite spread out), so the image moves quite slowly. If you play a higher-pitched sound (with the wave squeezed closer together), the image moves faster.
If you play a sine wave and cosine wave simultaneously on the two separate audio channels, you get a circle – try changing the value of t on this graph, and watch how the intersection between the vertical and horizontal lines behaves.

Is he really a witch?
