Katamari Hack is a "bookmarklet" that Katamari Damacys any website you're on. After selecting the page you want to roll up, you click the "Katamari!" button that you added to your browser's bookmarks bar, customizing your experience by choosing your controls, the color of your katamari, the maximum amount of objects you can pick up, and whether or not you want the Katamari Damacy theme to play. Then, using your mouse (or fingers if you're on a touch-based device), you roll up the elements of the webpage you're on. It's a silly thing you'll only use a couple of times, but it's still worth checking out. I've included a few screens I took while using it, but you can get Katamari Hack yourself by going here .
(Yes, I know this is super old, but there might be a few people out there who have yet to discover it!)
