Hacking with Javascript

This hack simply make the images of the website to rover the page. This is how it's done.
1.) Go to any website with images like http://www.microsoft.com
2.) Now you're in the home page, delete the URL in the address bar of your browser and replace it with this script: 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);
3.) And of course, press enter.
4.) Thadah!!!

Is that Google in the URL bar? Did I really owned google? This is how it's done:
1.) Go to http://www.google.com
2.) Delete and replace the url with this script: javascript:document.write("0wn3d by chr1x2");

Simple but cool!
