cqueues is a comprehensive event and networking library for Lua 5.2 and LuaJIT using modern Unix O(1) polling facilities. It includes libraries for buffered socket I/O, SSL/TLS sockets, DNS querying, signal handling, threading, file change notification, and X.509 key management. It natively supports Linux, *BSD, OS X, and Solaris systems without third-party dependencies, and is interoperable with any event loop that accepts plain descriptors, or is usable standalone.
Avoision is a very simple arcade-style game. There's no story, no fancy graphics, no campaigns--just frantic, high-speed gameplay. Gameplay consists of moving a green block around with the arrow keys. The goal is to capture the red block before the timer runs out to score points. You must avoid all the white blocks that appear as you progress through the game.
CorsixTH is a clone of Theme Hospital. As computers evolve, we risk losing some classic games. Bullfrog's Theme Hospital, published in 1997, is a classic simulation game, but getting it to run natively on modern operating systems is getting progressively harder. CorsixTH aims to reimplement the game engine of Theme Hospital, and to be able to load the original game data files. This means that you will need a purchased copy of Theme Hospital, or a copy of the demo, in order to use CorsixTH. After most of the original engine has been reimplemented, the project will serve as a base from which extensions to the original game can be made.
Scrupp is a 2D engine that uses OpenGL for hardware-accelerated visualization. All of its functionality is exported to the Lua programming language. Using Scrupp means writing Lua scripts. It features support for movies and networking and enables run-time image creation using Cairo.
