    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.

Newbie here. Would have loved to add some alpha but no room :)

Heavily inspired by: http://paulbourke.net/fractals/clifford/
u/sigveseb

A trick for alpha is to fillrect with a width < 1 ;)
u/joeytwiddle

You can save 3 chars with: c.width|=e=1.9 (doesn't seem for work for negative d)
u/joeytwiddle

I did you a low-res remix: https://www.dwitter.net/d/4842

Thanks for the tips and this remix!
