In case anyone here is interested, it's a project to finish an OS that Apple was working on and for some reason scrapped. The website is: http://www.rhapsody-project.tk/
You can read a lot more about it there. I myself have not done much looking into the project, but my brother is a big fan of it.
Basically right now the project needs more people who would be willing to test the OS.
I highly doubt that you'll have much luck finding the OS as it's illegal, but it's still a very cool project.
If you're interested in it just send me a PM and I'm sure my bro can tell you more about it.
