They say imitation is the sincerest form of flattery. There are dozens of themes being created every day for Windows 7. As a regular visitor to DeviantArt's website, one nice Apple MAC Leopard OSX visual style for Windows 7 is called LIM Leopard for Windows 7. Shown is the Nexus Dock launcher panel. The RKLauncher is another good dock launcher. Below are the results....and a link where you can find the theme...
