Interesting idea but I was totally caught off-guard by the automatic tweet posted when I clicked on the little birdy in the middle. Really not cool. Deleted the tweet immediately. At least let someone know you're going to be posting a tweet so that they can decide if they're game.
Sorry. In the middle used to be a font switcher, but it didn't turn out that well, so I replaced it with a custom tweet button. Yeah, maybe it would be less intrusive to move it to the bottom.
To create the head shapes, the position and rotation of each letter is defined with CSS transforms (see heads.css). To get the right values, it's mostly trial and error. But to make it a bit easier, I created a little helper script that let me drag/rotate each letter with the mouse and then copy the value to be used for those CSS transforms.
