    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.

This one looks better in Chrome than in Firefox
u/joeytwiddle

Firefox users: please replace 50% with 33% or 66%

I guess this is exploiting rounding behaviour. RGB clouds emerge first, CMY later.
u/joeytwiddle

It has stopped working in Chrome. Now Chrome needs the same fix as Firefox!

another 4 bytes can be shaved but it will take longer to draw ;-)
