    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)!

If AnanFay remixes this, then yes, it will eventually write The Complete Works of William Shakespeare.

For 81byte slow running version lose the subtle camera waving, drop multiplication from t and the last AND operation from height function :)
u/p01

That makes it 77bytes if use a single for loop with a width of 64 and increment of 1/64 ;)

Someone should use this for a black metal video. Even the resolution is perfect.
