During FOSDEM 2007, a live CD using the Etoile desktop environment was demonstrated, and this live CD can now be downloaded (screenshots inside the link, boys and girls). Etoile is a desktop environment based on GNUstep. "This is the 0.2 prerelease that we worked on at FOSDEM 2007. There's still quite a lot of problems on it (check the bugtracker), so we expect the final 0.2 release in about a month. In the meantime, feel free to download the iso and to play with it."
