OS X Theme for Ubuntu

Remember to try it out on Ubuntu machine at home. Though I'm not sure what the point is... I use mostly Macs instead of Ubuntu on desktop not because I think the UI is any prettier, but because there are apps on Mac that don't exist on Linux. In particular, iTunes and Quicktime, but also other weird ones like Quicksilver.
