I would like to second this proposal. For those of us who know Orio, we know well of his experience and capability with not only Xfrog, but with Vue d'Esprit, as well as other programs. Xfrog is rapidly building momentum and will be a viable force in the new generation of 3D organic (as well as abstract) 3D computer modeling programs. Xfrog does trees well, but does so much more too, equally well. Please cast your vote here, to add this impressive program to our ever-increasing list of 3D learning resources, and say "Yes!" to the Xfrog forum!
