FreeBSD-based operating system. The idea of the system is to incooperate some of the general ideas of the Navi system from Serial Experiments Lain in a fully functional BSD compliant system.
The finished OS will have some changes in the X system and a WM of its own. Future ideas for voice recognition is underway, and a 3D login interface is aready in the beta stage. An interesting project, since the Navi system has a lot of nice ways of solving different GUI problems, in a totally different way than the traditional systems solve it.
