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.

  • Fibonacci spiral
  • u/katkip
    Owwww woottt thats awesome
  • u/rodrigo.siqueira
    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!)
