Cool javascript trick

Paste the following code in your address bar, especially on a website that have a lot pictures of the same size. As far as my computer is concerned, this piece of code works well in my Firefox browser 2.0 but not in Internet Explorer 7.0. It might work the other way round (works in IE7 but not in Firefox). Hopefully, it will work on either of those browsers.

javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval('A()',50); void(0);
