testing remix of d/1948

u/IV

correction: remix of d/19498. The problem with this is in replacing the canvas. Any attempt at a remix will fail to get the context. But it is shortest :D
u/nikoloffgeorgi

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

nothing you cant do better with the canvas. try this: with(c.getContext('webgl'))(enable(0x0C11),scissor(i,i,i,i),clearColor(C(t),S(t),t,1),clear(16384))
u/IV

what we need is a glitter, with a quad shader set up and then we can play with 140 chars of a fragment main
u/IV

u/nikoloffgeorgi game-on! i did this: d/19541
