sweet forest, but I prefer to think of it as "Stop rules are for the impatient"

I thought you weren't afraid of computing time ???

Looks great. And I agree there's something more "pure" about a grammer without stop rules. Infinite recursion for everyone!

Also, what's with the circles? Bird's nests?

Are you kidding ?
It's mistletoe, I'm definitive about that. (don't look at first image)

Heh. We don't have many deciduous forests around here, guess I've never really seen it before when it wasn't Christmas.

Now I understand why some of us do pinewoods, and other winter trees.

Should I precise I'm still working of leaves ?

I begin to find no words....

( I'd almost think it could be nice to have a monthly poll vote BUT i in no way do want to see creativity bound by any kind of results )
