    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.

Really wanted this to use a more sophisticated random character generator but I couldn't figure out how to fit it. Thanks to Yonatan for golfing tips (.map instead of .forEach and S being a string instead of an array)!

May not work in browsers that don't have "**=", but there should be enough room to replace "s**=m" by "s=s**m".

I couldn't fit in scaling by "s", either via x.font or via x.setTransform or x.scale. This is also broken on iOS Safari because x.filter needs the trailing semicolon on that browser.

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.
