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.
