    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.

:) I actually started out with a similar idea, trying to describe it as a function... but then I got too greedy and wanted it to be exactly the same as the GEM version. This feels pretty close to the more modern logo though!
