LuaSprite
LuaSprite is still in development.
It is a graphics environment for programming in Lua especially targeted at those who are learning to program or desire an environment for easily tinkering with cross-platform graphics code, especially for games.
LuaSprite, will be open source and free, but an extended version with additional capabilities will be offered under a second license which will allow use within non-opensource products so that those who learn using the library or need its features can continue using it for their own for-profit projects.
If you are interested in finding out more, requesting a feature, collaborating, or being notified when LuaSprite is going to be available send me a note at luasprite at ranton.org.
