    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.

u/jgobi

it's very pleasing to vary the Math.PI's exponent and see what happens. particularly i liked a lot the 9 (d/19684), 11 and 19. I tried to adjust this to auto change this, but it always get bigger than 140 characters ^^"
u/jgobi

ops, the https://www.dwitter.net/d/19684 is for the 11 variation
