    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.

Brilliant :D

Hmm, there is actually quite a bit of space left. Can anyone make it follow the mose?

Or wait... that would require a lot actually, nvm, i doubt it will be feasible.

I could get it to chase the mouse but could not keep the edge detection: https://www.dwitter.net/d/2495

The slow turning is exactly what i was thinking of. I've already asked once, but why not again? Is anyone able to compress the last 12 characters in joeytwiddle's 2495 with the slow turn addition?
