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+Math.random()*10;
DIS.top=Math.cos(R*y1+i*y2+y3)*y4+y5+Math.random()*10}T+=0.02;S=Math.sin(T);R+=S}
setInterval('A()',5); void(0)

7.) Press enter , see the magic.
