Hittade det inte, så det blev till att skriva ett eget:
javascript:(function(){tp=2*Math.PI; a=0; b=Math.random()*tp; c=Math.random()*tp; m=document.images;l=(ml=m.length)/tp;setInterval(function(){a+=.1;b+=.032;b+=.026;h=(window.innerHeight?window.innerHeight:(document.documentElement.clientHeight?document.documentElement.clientHeight:document.body.clientHeight))/2;w=(window.innerWidth?window.innerWidth:(document.documentElement.clientWidth?document.documentElement.clientWidth:document.body.clientWidth))/2;for(i=0;i<ml;i++){s=(e=m[i]).style; s.position="absolute";s.left=(w-e.width/2+Math.sin(c+i/l)*Math.sin(a+i/l/3)*w)+"px";s.top=(h-e.height/2+Math.sin(b+i/l/3)*Math.cos(a+i/l)*h)+"0px";}},10)})();
