Arcan
Powerful development framework for creating virtually anything
Arcan is a powerful development framework for creating virtually anything from user interfaces for specialized embedded applications all the way to full-blown standalone desktop environments. At its heart lies a robust and portable multimedia engine, with a well-tested and well-documented Lua scripting interface. The development emphasizes security, debuggability and performance, guided by a principle of least surprise in terms of API design. For the main engine there has been quite some refactoring to reduce input latency; better accommodate variable-refresh rate display; prepare for asymmetric uncooperative multi-GPU and GPU handover; explicit synchronization and runtime transitions back and forth between low (16-bit) to standard (32-bit) to high-definition rendering (10-bit + fp16/fp32). -

Hipe: Hypertext Pipe
Display server for Linux based on Webkit and HTML layout capabilities.
...Annoyances like page refreshes are done away with. Why use HTML? Because it's ubiquitous. Everyone is using it and everyone already knows how to use it. Why use a browser engine for an OS-level display layer? Because content rendering and layout is *hard*. Decades of development have seen web browser engines become very capable indeed. Meanwhile, native OS display capabilities have lagged behind. Time to fix that. -
