good remix of d/10212 :)
u/keithclark

Yes! It's totally based on your dweet yonatan - thanks for the link to the original. I found this in a text file from last year but couldn't remember who did the original.
u/keithclark

I also had this version: for(k=i=1e3;z=--i/9;x.fillRect(k+S(m=z%1&&k*j|5)*r-z*C(j)*6,540+C(m)*r-z*S(j)*4,s=5e3/z,s))j=i/k+t,r=1e4/z,x.fillStyle=R(a=99+S(j*9)*99,a,a) but wasn't happy with the rail
