  • pavel: I call fill just once, the black bits are a single connected shape that zig-zags, the messy edges are hidden offscreen.
  • pavel: I use 1/(1+9e9**x) to smooth step but even rows step twice in one cycle which is done by adding (j|t)%2 as offset.
  • pavel: In hindsight ~~x+(x%1)**9 is better for multi-smooth-step animations.
