yeah this is pretty neat, I love that taskbar, Sometimes the windows 7 taskbar will pop up on top but that is fine, you can put the windows 7 taskbar on top and unlock it then use autohide feature on Windows 7 taskbar
Why make your computer look like Mac OS X when you can just buy Mac OS X? You need to download Stardock ObjectBar to add a mac-like menu bar on the top, a Mac wallpaper and some Mac cursors as well. As for the dock, it's just RocketDock with the taskbar hidden. Nothing special.
