tip: you can get rid of the initial "reference error: X is not defined" error by hijacking one of the globals that you're not using in your dweet: R, T, C, S

a webgl that does something, and leaves 39 chars to play with

whoops, meant to put that in the remix note, then the remox failed, bad day ;)

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))
