A brute force approach to circle packin… by kchplr

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.

A brute force approach to circle packing. A lot of thanks to jsgolf slack channel residents @xem and @qfox helped **a lot** reducing my original 167 characters attempt ( https://codegolf.tk/a/152 ), as in actually doing most of it. I honestly did not think reaching 140 bytes was possible.
