Lua Showcase

Lua is used in many products and projects around the world. Here are some highlights. A different selection is shown every day.

GitHub World of Warcraft Solar2D Angry Birds
GitHub uses Lua scripts in the infrastructure of GitHub Pages, its static site hosting service. Players of World of Warcraft use Lua to customize the game interface. Solar2D is a free Lua based game engine with focus on ease of iterations and usage. It is a fork of the well established and widely used Corona SDK game engine. The widely popular game Angry Birds is mostly written in Lua. See a talk by Jaakko Lisalo at the Game Design Expo 2011.
Wikipedia Grim Fandango Celestia VLC
Wikipedia uses Lua as its template scripting language. Read the announcement. "Grim Fandango was the first game that shows Lua could not only be used to make a good game, but that it could be used to make some of the best games ever." (cited here; see also this) Celestia is a real-time 3D visualization of space that can be scripted with Lua. The widely used VLC media player is scriptable in Lua.
