JavaScript in address bar, trick to make images in a web page dance

I recently found this funny JavaScript code which will make the Images on any page go in a ring like dance. I got it through an e-mail forward, so I don’t know whom to credit. All you have to do is
1. Go to an Image rich page (eg:search for flowers in Google Images)

2. Paste the following Javascript code in the address bar and press ENTER (GO).

Copy this script and paste on adress 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)

What happens :

Let us examine the script to know what happens. In all the Browsers if a JavaScript code is embedded in the adress bar it can be executed as if it were in the page itself. This has also caused many vulnerabilities. That is a long story so lets come back.

The JavaScript makes an Array DI with all images as objects, then finds the number of images in the page and goto a loop which will change the position of the images one by one to a position given by the X and Y cordinates DIS.left=Math. sin(R*x1+ i*x2+x3)* x4+x5 nad DIS.top=Math. cos(R*y1+ i*y2+y3)* y4+y5}R++ }setInterval( ‘A()’,5); This goes on and we see the images going in a bend dumbbell.
