Hi! I'm a graphic designer - turned web designer - turned web developer - who is currently trying to turn into a mac developer. I've nearly done programming my first app. Is a very, very simple application but I'm happy because I'm learning a lot of new stuff. The problem is: I don't like how it looks.
