You can only install this on windows in a VM (like Virtual Box). You also can't install it directly, you would need a Linux distribution as well. It would be easier to wait until Ubuntu or Fedora releases a new version which contains this version of GNOME. Desktop Environments on Linux are basically GUI themes.
Not only are they GUI themes, some desktop environments come packaged with different utility software. (e.g. Gnome comes with GTK-based utility software like Gedit, and KDE comes with KDE-based utility software like Kwrite.
