    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Blancmange curve (Takagi curve) #fractal

u/rodrigo.siqueira

Based on the discussion: "Unexpected link between pure mathematics and genetics." https://news.ycombinator.com/item?id=37011776
u/rodrigo.siqueira

This fractal curve described by Teiji Takagi in 1901 is constructible by midpoint subdivision. It's called the blancmange curve, because it looks like the French pudding dessert. Implementated here from the "blanc(x)" function: https://en.wikipedia.org/wiki/Blancmange_cur…

Rotating pyramid. Can anyone figure out how to make the colors smoothly darken so that it loops perfectly?

u/yonatan

with(x)for(i=3;--i;beginPath(fill(lineTo(960*i+320*(i==1)*(t%6-3),1080))))fillStyle=hsl(0 50%${i*(6+t%6)}%,moveTo(960,340),lineTo(0,1080)
u/yonatan

sorry, that's not quite right
u/f8f82804

it's great, see my remix
u/yonatan

hsl(0 50%${50+((i==1)-(t%6/6))*9}% works, but a bit long
