Re-make of d/8422 with the "u" variable… by Agnes

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.

remix of d/8422 by u/Agnes

function u(t) {

i=new Image();d=[...c.toDataURL()];for(j=1+~~t*100;j--;d[~~(Math.random()*d.length)]="a");i.src=d.join("");i.onload=()=>x.drawImage(i,0,0);

Re-make of d/8422 with the "u" variable re-named "d" (having a variable named "u" breaks your dweet in most views)... interestingly, this violates the new cross-domain content policy!

Could it be the toDataURL() ?

I think we realised it's not actually the cross-domain policy breaking it but something else. The console errors are when you try to load corrupted PNG data, which this produces pretty often.
