Theming was where I got started. Of course back then you didn't have nearly the flexibility that todays modern window managers allow. You had to edit dotfiles, or even hack the code itself to make it look 'just right'. But these days themes like BlueSteel, Blueheart, AbsoluteE, BrushedMetal and Cyrus each help to make your desktop a cause of significant drool from our coworkers. Which one is the best?.
