LuneOS
LuneOS is a mobile operating system based on the Linux kernel and currently developed by WebOS Ports community. With a user interface based on direct manipulation, LuneOS is designed primarily for touchscreen mobile devices such as smartphones and tablet computers. The OS uses touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to manipulate on-screen objects, and a virtual keyboard.
LuneOS is the open source successor for Palm/HP webOS where the user interface is rebuilt from scratch by using the latest technologies available. It is not intended to compete with iPhone or Android on features. All devices can have a LuneOS port if they have a CyanogenMod ROM available that works.
As of 2014, the system was still in alpha, with some internal hardware not supported and some applications still buggy. It can be updated without a reinstall. It has the feel of the webOS formerly used on Palm and HP hardware, including a cards-based multitasking system and universal search. It has been described as "a niche mobile operating system maintained by enthusiasts".
