Tree factory is pretty cool but I haven't started playing with it fully yet. It has a series of stock items and grows limbs with a fractal routine. The stock trees are pretty good. I haven't played much with making my own trees. Supposedly you can do some cool stuff with it. Great for making trees for Bryce for example or even Poser. Do NOT buy creature creator. All it is is a basic model (very similar to the poser P3 male I might add) and a bunch of limbs and such. Basically its like 7 or 8 models in which all the limbs are interchangeable. The only good thing is they do have a nice anime girl model that could be converted to Poser ina few hours.
