Lua Showcase

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

Celestia LÖVE Grim Fandango World of Warcraft
Celestia is a real-time 3D visualization of space that can be scripted with Lua. LÖVE is a free framework for making 2D games in Lua. "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) Players of World of Warcraft use Lua to customize the game interface.
Neovim Volvo Angry Birds GitHub
Neovim is a popular hyperextensible Vim-based text editor that supports Lua plugins. Volvo cars like the V40 Cross Country embed Lua in their combined instrument panel. The widely popular game Angry Birds is mostly written in Lua. See a talk by Jaakko Lisalo at the Game Design Expo 2011. GitHub uses Lua scripts in the infrastructure of GitHub Pages, its static site hosting service.
