    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.

Wait, how did you call .join without parentheses?
u/jylikangas

That's ES6 stuff - I'm passing the function a template literal by using back-ticks
u/AnnanFay

Hmm, that's a neat trick.
