If you are new to Linux, you should not be using the Metisse version. It is a 'proof of concept' version to show what Metisse will add in the release planned for this spring. I am on several Mandriva mailing lists, and here is the information I received:
Metisse is a window management tool in 3D developed by two French researchers
from the In Situ project, available under the GPL license, for Linux only.
Contrary to a 3D graphical environment (a "cube"), Metisse offers an
innovative way to manage windows: only the windows move, making the possible
variations endless. Metisse is not a 3D desktop but a Human-Computer
Interface (HCI) technology.

functionalities of Metisse:
Mandriva decided to integrate Metisse to its new distribution, Mandriva
Spring, to be released next spring. Associated to the 3D desktop already in
the Mandriva Linux 2007 distribution, Metisse will make Mandriva Linux the
most up-to-date distro as far as the graphical environment is concerned. The
integration efforts made by Mandriva renders Metisse available for all, for
an even better comfort of use.
In addition, Mandriva released a Metisse Live CD, based on Mandriva One 2007
GNOME. It allows anyone to discover and familiarize with all the outstanding
functionalities of Metisse. The future is now!
