I have a class on my college on which we can choose what to do as a final project the only requisite being that we need to do something we haven't covered in any class at the degree.

I want to be a Gameplay programmer and saw that many offers ask for Lua, then I think this is an opportunity to do something in Lua and learn the basics but I don't know what to do, any ideas of a simple project I can do in Lua or a framework that uses Lua that can teach me the basics of it?

Tl;Dr: Want to do a small project in Lua, have no idea what to do tho. Ideas?
