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.

    Familiar!? Just realised that this is equivalent to an elementary cellular automata with a 2 state history.

    Owwww woottt thats awesome

    SOURCE CODE: for(c.width|=i=9;i--;x.transform(k=.62*C(a=S(t)*1.57),s=.62*S(a),-s,k,w,w))x.rect(1,1,x.lineWidth=w=300,w),x.quadraticCurveTo((z=150)+S(t)*z,z-S(t)*z,w,w);x.stroke();

    very cool golden ratio / rectangle fx. (never seen before like this, great!)

  • best fullscreen. Couldn't have done it without the help of the dark knight, who prefers to remain anonymous. :)

    yeahhhhh!!!!! cool

    there's an odd bug in chrome where if hardware acceleration is disabled, or the dweet appears far down the page, the arcs close their paths and create unwelcome diagonal lines. I have a more robust version but it does not fit in 140b.
