^ DAMMIT! You should have posted this much earlier, as I saw it on 4chan weeks ago.
It seems like I always find out stuff before everyone else.
Here's a variation that makes the images go much faster:
javascript:{var R=0,x1=.1, y1=10000, x2=.25, y2=.24, x3=1.6, y3=.24, x4=300, y4=200, x5=300, y5=200, I=document.getElementsByTagName("img"), L=I.length; setInterval(function (){for(var i=0; i-L; i++){var S=I[ i ].style; S.position='absolute'; S.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; S.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++},5); void(0)}
As said above, you need to remove some of the spaces because Ultimate Metal has a stupid spacer when there is too many letters in a sequence. It's quite annoying and I hope it gets fixed sometime because it really ruins some things.
EDIT: It doesn't seem to work on Ultimate Metal btw. Try google images or something.
