Sun has launched some times ago the interesting Project Looking Glass, a new revolutionary Java technology-based technology that will bring 3D windowing capabilities to the desktop to offer a far richer user experience for work and play.
This project was for a long time only reserved for few "lucky" people, but now Sun has launched a great idea: a Live CD to try Looking Glass. This cd is based on a Knoppix derivate with better 3D hardware-acceleration and the version 0.6.1 of Looking Glass.
Obviosuly, it's on a very early stage so don't imagine to launch the cd and see a wonderful 3D desktop engine. During the booting phase you can choose between KDE (standard for Knoppix) and Looking Glass and you're ready to go.
I hope that the project will be improved soon... I think it's a great way to launch these new revolutionary features for Sun.
