help me evangelize Lua

[Thatcher Ulrich <tu@...>]

I need an easy-to-use interactive Lua app for the other coders and artists
at my company to play with, to help sell them on using Lua in our next
game, get them excited about it, and start the learning process along.
The ideal thing would be an interactive console, with some hooks for doing
simple 2D graphics. The lead asked for  "Something nice like Lua running
Flash or Logo would be ideal."

Has to run on Windows.  I'm sure there are a thousand apps like this, so
I'm wondering if people can point me at a good one.  Titmouse seems like
the ideal UI, but I'm not sure how to hook it up with graphics.

Pointers & advice appreciated.
