testing remix of d/1948 by IV

function u(t) {

c.width=1920 // clear the canvas
for(i=0;i<9;i++)
x.fillRect(400+i*100+S(t)*300,400,50,200) // draw 50x200 rects

} // 122/140

    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.

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