    smaller... with(x)for(c.width|=j=3;j--;beginPath(fill()))for(i=4;i--;fillStyle=hsl(${j?(t+j|0)*90:45} 90%${25+20*S(j?a:2)}%)q=j&&i<2,ellipse(960,q?760:340,300,99,0,a=((q?j-i:j+i+1)-t%1+.5)*1.57,a)

    nice. the lack of perspective is an opportunity ;) i have this for(c.width|=i=6;i--;x.fill())for(x.beginPath(j=4);j--;x.fillStyle=`hsl(${60*i},99%,50%,.3`)x.lineTo((w=960)+S(p=(A=Math.atan2)((a=[S(p=1.57*j+.79),C(p),.7])[i%3]*(l=i<3?-1:1),a[(i+2)%3]*l)+t)/(Z=(C(p)+3)/w),540+a[(i+1)%3]*l/Z)
