I'm surprised there's very few WIPs for the challenge. I say let's get it on!

It turns out Stefanos idea for the challenge is a REAL challenge! Not only do you have to think of treelab, you gotta learn skylab, and terrain fractals as well. Today I spent some time on the skylab and treelab, boy I learned a lot! Not much luck, just one tree =( . So here it is so far, semi-transparent leaves. Not much of a WIP really, Sigh!

I was trying to get the sun in the right spot and right amount of transparency on the leaves. Hope you guys are making better progress.
