    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.

Magical sigil generator. Replace Z with any word (lowercase only). It's a small remake of: https://sigilscribe.me/

You can save 7 chars by doing f=i*t,X=f*f%9,Y=X*f%5 in these instead of Math.random. It seems random enough.
