I'm going to get the upgrade eventually, but I was curious -- with the new tree modeler, how wide a variety of trees can you make? Is it basically "pine tree" or "elm tree," or can you make palm trees, spooky haunted-house trees, rain-forest giant, bushes, ferns, what-have-you? If any of you have played with it and have a moment, I'd really appreciate hearing from you. Thanks!
