I've just finished work on my first ever WordPress theme. I call it "Stylus". Initially, I just made some modifications to "Contempt" by Vault9 but it ended up becoming less of a personal customization and more of a theme in itself, so I decided to release it publicly. It's nothing fancy, just plain, simple and rather elegant, if I do say so myself ;).
