    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.

Substring explorer

u/Agnes

Every frame, this tries to find a random substring of length L that appears somewhere in the member variables of the Javascript canvas object c. If it finds a match, L is increased by one.
u/Agnes

I think this crashes if W.length gets too long but I don't think it's ever going to get much further than 5 in the lifetime of the universe so we're fine.

#default, but only when you're not looking at it

u/Agnes

... maybe this doesn't work at all. I don't know how to tell if it's a default when I'm not looking at it
u/cantelope

... the shim will halt when offscreen, so, it likely cannot run
