First, go to google.com or to your myspace homepage if you have one. It works pretty cool on either site.
Next, cut and paste the following code and put it in your address bar
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);
Now press enter.
