Looks nice with n=_=>S(t*_)*99+166 and R(n(1),n(2),n(4)) as the colour

u/donbright

best dwitter torus?
u/sigveseb

nice!
u/keithclark

Why not use x.fillRect((k-a*i-b*a*j)*z+899,(i+b*j+a*k)*z+500,6,6)? it renders faster and is smaller
u/mxfh

Print and connect the dots. Or do it on screen for lasting impact.

Lovely, i agree there is something appealing about the aspect ratio of that rectangle
