As part of #circlechallenge I go back to the old rational parametrization of the circle from Wildberger's "chromogeometry", which has elements of Euclid. Each frame draws rational points on a circle, and each frame the radius gets bigger. All of the patterns are a kind of optical illusion.

u/donbright

changing '2' and '3' to different numbers will give different patterns

Wanted to save some more (1-4) chars by changing this: x.F=x.fillRect;with(x) ... but i can't get it work... n-joy...

You could do i=8,x.F=fillRect to save 2 chars. Hope I'm not too late!
