    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.

u/IV that's really cool. i wonder if anything beyond animating the color uniformly can be done within 140 chars
u/IV

This is 140 chars. If you can mix it with your moving cubes code and golf it down, youre winning! t||c.replaceWith(g=c.cloneNode());i=t|0; with(c.getContext('webgl'))(enable(0x0C11),scissor(i,i,i,i),clearColor(C(t),S(t),t,1),clear(16384))

u/nikoloffgeorgi I did this: d/19541, (but I cant do comments properly yet) Your turn!
