Enlightenment started as a project to build a Window Manager for X11. That was way back in 1996. It has grown much since. It still produces this Window Manager, but it has evolved to also cover Mobile, Wearable and TV UI needs for projects such as Tizen as well as traditional the “desktop” UI.
Long ago Enlightenment was just a project to make a Window Manager for X11. It has grown a lot since then to well over 1 million lines of C code in just the EFL libraries alone, as well as a Window Manager, and a set of applications. There is a vibrant and active community of developers and users who work on the code, use it every day and enjoy their environment.
These provide both a semi-traditional toolkit set in Elementary as well as the object canvas (Evas) and powerful abstracted objects (Edje) that you can combine, mix and match, even layer on top of each other with alpha channels and events in-tact. It has 3D transformations for all objects and more.
