    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.

haha best remix of default

Heh, thanks! Though, I'd argue that techniques like these are probably "illegal" due to use/abuse of things external to the canvas. And dweets like these are bound to eventually break as the Dwitter runtime is updated. But, hell, this is fun!

I think this is Kosher. You are manipulating the canvases style after all. Also you don't need the with c.style.background= is 5 char shorter

Ah dang. That's a vestige of trying to add more effects to this :)
