Thinking about it, John's right. This is a cartography forum, but in reality its a huge collection of all different kinds of creative person. Even I have dabbled with 3D. There are all kinds of people like Falconius, Jo and Ilanthar around who all use Bender and Sketchup (and those are just a few names straight off the top of my head.)

I bet you're going to really show us all up in the end with all the 3D tree models you are about to create
