    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.

Some nice math for the 270 initial radius: The half-height is 540, this must equal r+r/2+r/4+r/8+...=r(1+1/2+1/4+1/8+...). Think about the bit in the brackets in terms of pizzas. You have a whole pizza, plus half a pizza, plus a quarter (half the remaining half), plus an eighth (half the remaining), etc. You have two pizzas! So 540=r*2.

Remix of d/11587. I remixed my other remix but that one was boring so I deleted it.
u/ciaccodavide
