This project is a little website trying to convert an uploaded picture to a postit grid. It's 33% HTML, 33% Javascript, 33% PHP (eaaaark.), the 1% left is this README :-).
It's far from being perfect, being totally focused on the machine the website will run on. However, excepted some hardcoded absolute links and a lot of PHP warning, it could work on any other webserver since we don't use anything fancy.
You can try this on http://postitwar.me .
Have fun !
