    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.

added transparency, hsl trick doesn't work on Safari it seems

u/joeytwiddle

u/pythech

yeah but then you'll exceed the character limit, oh well
u/pythech

the other browsers silently accept the 4th parameter when they should not. That's a bit trickery for me, or at least that's what I meant. I could phrase it a better it seems, thanks for helping anyway, my bad :D
