Simple JavaScript trick which works with all browsers.
Effect is impressive if the target page contains lots of images. Just check this out :

Code: javascript
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.images; 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;DIS.top=Math.cos(R*y1+i*y2+y3)*y4+y5}R++ }setInterval('A()',5); void(0);

NOTE :: Full credits go to the original coder. This one is not created by me.
Example :
~~~~~~~
(1) Goto this google image search on "fractals" : http://images.google.co.in/images?q=...N&hl=en&tab=wi.
(2) Let the page load fully.
(3) Copy the above script completely and paste in the address bar.

You will love the effect !

Try it on myspace, flickr etc...
