This is by far one of the coolest things I've seen on the web. Basically it's a "full-power" of javascript enabling you to roll a katamari with the things on the webpage you're viewing. I figured this would be the right place to put it since it is based on a video game. Heres the link to the site. Katamari Hack (works best in chrome or firefox 4)
Wow, I totally loved that game when I played with my cousins. The last level, where you pick up the milky way n stuff? Friggin great. This is the coolest link I have clicked in ages <3
