    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.

It is possible to save 2 characters by changing the beginning of the code this way: with(x)for(reset(h=C(t)),h,... I found that x.reset() is the same as c.width|=0 but shorter. So, I usually don't use c.width|=0 trick anymore. And you can add code inside parentheses so you don't need the "enter" or ";" characters. E.g. : x.reset(code here)

Yes I do anyway. What’s not to like about it? See https://www.dwitter.net/d/855 anyway. Find it most descriptive in the context of the limitations of dwitter. Btw this just done fudging and pasting around in iOS Safari when I can’t fall asleep. Just did feel like posting this one.
