The Lumina Desktop Environment is a lightweight system interface that is designed for use on any Unix-like operating system. It takes a plugin-based approach, allowing the entire interface to be assembled/arranged by each individual user as desired, with a system-wide default layout which can be customized by the  system administrator. This allows every system (or user session) to be designed to maximize the individual user's productivity.
