    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.

Massive props to JWinslow in the Discord for doing almost all of the golfing! The last 15 or so characters were removable because 1.57 is an OK approximation of Pi/2 and because the dimensions were scalable by four in the transform.
