golf'd slightly harder on general principles: i=frame;for(j=1080;j--;x.fillRect(i,j,1,S(k/9),x.fillStyle=R(k,j,i)))for(a=b=0,k=35;k--&&a*a+b*b<4;a=c)c=a*a-b*b+i/540-2,b=2*a*b+j/540-1

This is freaking amazing. Even if it would have taken you 1000 characters
u/iverjo

Thanks bakkot! I golfed your version even further down to 134 characters: for(j=1080;j--;x.fillRect(i=frame,j,1,S(k/9),x.fillStyle=R(k,j,i)))for(a=b=0,k=35;k--&&a*a+b*b<4;a=c)c=a*a-b*b+i/540-2,b=2*a*b+j/540-1

Feel free to play with the colors! There's room for improvement

I must commend you! Did my research and got a working mandelbrot, but to golf it to 140 and get the speed is very very difficult! Wow. I will study your dweet now :)
