I think it takes an actual "simple" project. Mine[1] was supposed to be trivial. Someone who comes now an see the 350 lines of code may think it was easy.<p>It wasn't. It's not even complete, and it took me several weeks of free time (much of which was spent simplifying my code).<p>[1]: <a href="http://www.loup-vaillant.fr/projects/ussm" rel="nofollow">http://www.loup-vaillant.fr/projects/ussm</a>
