Adobe Lightroom and Lua

This morning I read a news that shocked me ... well just a little shock from a developer point of view :-)

The software is Adobe Lightroom and the news is that it is driven by 100,000 lines of Lua code! (This represent about 40% of its total code).

Well, if you don't know Lua, this link can help and if you want a better blog entry about this topic this is another link for you.

I admit that maybe I have underestimate the power of Lua, but it seems that Mark Hamburg from Adobe really know how to reveal its power.
