Infinity loop by flipnow

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.

Nice. I tried re-aranging this a bit: for(i=44;i--;x.fillRect(960+600*d,540+600*d*S(p),25,25))x.fillStyle=i%2?'#36c':'#fff',d=C(p=t+i)/(1+S(p)**2)
