I... I've spent almost two full weeks on getting this algorithm right.
They're aperiodic tilings of rhombs, which can be constructed through (de Bruijn's) method of multiple grids, which is effectively the same as projecting a 5/6/7/8/9, etc cube grid onto 2d. Shows up in nature as quasicrystals.
Tried to get this working in seexpr, failed miserably. Still spent like 2 days on getting something visible in #Krita.
I am so tired, but happy.
