  • u/pavel
    Also a pretty generic ray tracing 'engine.' Change f to trace other things.
  • u/pavel
    Style remix, no idea how the code I'm remixing works yet. It does not look to do ray tracing so its clearly better.
  • u/primo
    The original uses z + ∂/∂y z for saturation, which looks about right tilted at or near ~26.5°.
  • u/pavel
    for(c.width&=i=10368;i--;x.fillRect(i&127,i>>7,f(.7),1))f=n=>(z=5-i/3e3-3*n)>S(Math.hypot(i/64%2-1,i/5e3-n)*9-6*t)?f(n+.03):--z*.4 is a better one, no weird view prism.

  • Zen garden. Circle patterns around the rock may represent waves or ripples in water.

    Japanese rock garden: "Developing variations in patterns is a creative and inspiring challenge. Achieving perfection of lines is not easy. Zen priests practice this to help their concentration."
