LuaMotif if a Lua binding for OpenMotif. The rationale behind it is to create GUIs in a declarative style as described in the article on http://www.vnode.ch/lua_gui. The source code is now on https://github.com/mbalmer/luamotif ready to be cloned. Remember to define some X resources for your applications, by default OpenMotif is now known for the beauty of the programs created with it ;) Enjoy!
