After the announcement by Canonical that Ubuntu would be moving to Unity for its interface, other developers have expressed some interest in porting it to their distributions just for fun. Now someone is working on openSUSE packages as well.
Nelson Marques, openSUSE contributor, began by porting some of Ubuntu's Indicators to openSUSE; many of which are available now in openSUSE:Contrib for 11.4 Milestone 4 and beyond. Marques stated that since many of the Indicators and dependencies are shared with Unity, he might as well try to package Unity as well.
