Katamari on your browser!

Tried it on Chrome and Firefox, said to work on Safari too. A clever programmer has designed a version of Katamari Damacy that you can play in your web browser on any web page.

Simply paste the following code into your address bar:

javascript:var i,s,ss=['http://kathack.com/js/kh.js','http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js'];for(i=0;i!=ss.length;i++){s=document.createElement('script');s.src=ss[i];document.body.appendChild(s);}void(0);

Use your mouse to roll up elements of the webpage. The ball gets bigger the more you roll up just like in the game. Something to distract you for a good 30 seconds.
