based on a particle simulation - you can see the positions encoded in the leftmost column
the particles actually are where two spheres touch and the odd marble shader connects them with circles
here's the link:
twigl.app?ol=true&ss=-NjEieE…
For general code golfing purposes I found it useful to also try the inverse of the golden ratio, sqrt(1.25)-.5 = 1/phi = phi-1. Sometimes this can save you a few characters for scaling.
And here's another example using twigl's "sound shader" capability.
x.com/2ndIteration/status/14…
While this is true for disentangling 2 variables, sqrt(e) is more suitable for 3 or more. I actually explored this because of grid cells, which our brains use to map physical and conceptual spaces. Here's a visual explanation using Lissajous curves:
