    smooth!
  • u/pavel
    Nice. Here's 126, maybe room for snowflake code with(x)for(fillRect(0,0,i=2e3,i);i--;)clearRect(50,9,!setTransform(s=2+i%7,0,0,s,i,i&&(i*i+t*s)*50%2e3-400),i&&!rotate(i+t/4))

    x.rotate is shorter, as usual for(t*=7200,i=420;i--;x.fillText(j=i/12|0,j,15*S(j*j*t),4))x.setTransform(1,0,0,i%12<6?-1:1,t%1980,t/24),x.rotate(i%12/.954)

    Thanks! I will use that method for the next iteration

    Dynamically swapping the draw order to get proper overlapping. Change i>960 to 1 or 0 to see how this works.
  • u/Qwitter
    cool, and thanks!

    If you stare a bit, you see white lines completing the circles - an optical illusion

    save 9 bytes for(i=c.width|=0;i--;x.fillRect(660+(p>>2)*200+130*C(a=.8+(p+p/4&1||-1)*(28.4*d+3*t)),240+p%4*200+130*S(a),d,d))p=i/120|0,d=i%120/9
