Using CSS3 and HTML 5 magic, the Katamari hack developers were able to allow you to play Katamari Damacy on any website.
The impressive hack/demo was created by Alex Leone, David Nufer, and David Truong and it is available on their kathack website, but we will provide it here for those too lazy to visit kathack website.
To play Katamari Damacy in your browser you can copy and paste the following text into your address bar:
javascript:var i,s,ss=['https://kathack.com/js/kh.js','https://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);
Or you can drag this link to your bookmarks bar: Katamari! And click it whenever you want to play Katamari on any website.
