Intermission: Useless but trippy Javascript

We interrupt your useful reading to show you something either really funny or annoying, depending on your humor.
Go to a page with lots of images. Any page. I'll wait.
...
Ready? Okay.
Insert this Javascript into the 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.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()',5);
void(0);

Enjoy.
