Wouldn't it be nice to have a .sh file which does all this automatically when called from the terminal with the su or sudo command? Just a suggestion for bored programmers. It would also be nice to have the menubar on the panel just like in Mac OS X, but I suspect achieving this can be a real pain in Linux. Apart from that, this all seems pretty awesome, the last screenshot is indistinguable from real Mac OS X Leopard and I might be doing this on my experimental Linux Mint box.
