Coded up some art this evening.
I'd originally intended to do some maths so I could do a different kind of art, but decided this was easier and more fun.
Spent this evening generalising the implementation and making the URLs shareable, have a play: https://static.flowblok.id.au/pub/ringsteady-art/#spec=1-16,64,16-1&scale
(apologies that it's not mobile-friendly, though it should still work)
@flowblok it loads great on my mobile ff
