    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.

was able to fit 11 letters, not all 26 though

Much better job than I did! I'm still learning, and didn't realize you could do it that way; thanks for demonstrating. For whatever it is worth though, not every character in Wingdings hangs low enough to be visible when printed that high. Capital C, E, F, R, and X don't, nor do lowercase d, h, l, n, s, or w. I didn't check numbers or punctuation.

I started out knowing basically 0 tricks, its been fun to learn.
