Chromatic Wheel flash thingy
« on: May 07, 2014, 07:36:31 am »

So I found this linked on imgur and was swiftly entranced by its patterns. I noticed that every so often a 'chord' of dots will all chime at once, and that the 'spacing' of the chord (i.e. how many 'spokes' the wheel formed at the time of the chime has) changes each time (couldn't figure out any meaningful pattern to it, though)

The following are copy/pasted from my musings after I posted this to my facebook (yes you could probably google them and find my facebook; no I don't particularly care):

Pattern (of spokes in chord wheels) appears to be sort-ofdescending?

approx. 50 dots total (further investigation makes me think 48, this makes sense from an 'octaves' point of view as well)

So the orbital period increases as you go out,but the absolute speed-on-screen peaks about halfway out. Orbital period and distance from the centre determine absolute speed vis a vis the eq'n (2*pi*r)/period so the period increases more-than-linearly as you go further out.

Anyone else got some insight into the patterns of this pretty thing?

I could make a mock-up to see if I'm correct, but I'm pretty sure I understand how it works.

Each circle turns a certain number of degrees each second, let's call this x. The speed of the one furthest out is x, the second 2x, the third 3x and so on. It doesn't matter what the x is, the patterns will be the same. The distance between two points in degrees is x*t

What you see as the "spokes" are when the distances add up to a full circle. For example a 6 spoked wheel. With x being 1 degree, happens when t = 60. The first will be at 60 degrees, the second at 120, the third at 180 and so on, with the 7th having the same location as the first, the 8th the same as the second. This continues and because of the way the circles are spaced away from the centre, you get the spokes.

The absolute speed and distance from the centre are completely irrevelant, as is the number of dots. Honestly most things are irrevelant, but it's very nicely presented with the colours and sounds.

Probably 48, so 4 octaves, chromatic scale.

We are doomed. It's just that whatever is going to kill us all just happens to be, from a scientific standpoint, pretty frickin' awesome.
