From ConTeXt wiki

LuaTeX is an extended version of PdfTeX using Lua, as an embedded scripting language. The LuaTeX project's main objective is to provide an open and configurable variant of TeX while at the same time offering downward compatibility.

The project started in the summer of 2005, and has since progressed into a first official early beta that was released during the TUG2007 conference in San Diego. Development is supported by a grant from Colorado State University and the TeX User groups.
