Try singing up for the ADC on Apple's site. Then you can download Darwin, and experience all of Mac OS X's glory, sans the beautiful Aqua interface... it'll be command-line only.
OR -- you could actually get off your butt, mow some lawns, get a part-time job, peddle for money, or any number of other small money-making things that are quite simple and buy your licensed copy of Mac OS X for the low, low price of $129 (compared to Microsoft's offerings) and help keep Apple and Apple users the law-abiding, upstanding citizens they are.
We don't need no stinking pirates using Apple. Take your illegal activities elsewhere, please.
