Huh, what the heck is that?
Well, it is simply the smallest/lightest/fastest scriptable gui widget I have ever seen.
If you are sitting around with a copy of DSL and you want to increase your geek threshold start trying to teach yourself some Lua and see what you could make -- we are using it for the control pannel and the 'media player'.
The project is over three years old now -- yet very few people even know it exists.
Oh, and Lua is very fast. It executes in about 1/10 the time of perl.
