This was a simple homepage from 2009-2011 I hosted on my personal domain, Ub3rK1tten.com.
It's like an anonymous graffiti board. Type something in the box, hit the button, and it would show up on an image on the homescreen like below. You could also tweet @Ub3rK1ttencom and it would show up, and messages posted on the website would be tweeted.
