Woo hoo!  I got to borrow it indefinatly. He doesn't use it, so it looks like I get to buy it from him.
  As for the marbles, I am too excited for words. I have it set up at home, and in just a couple hours of playing, it's like the Bryce I always dreamed of.  So far I've found the boolean shapes, the physical material editor (is it hard or "bouncy") and a ton of other things.
  I may be asking for help on spline editing so I can make curves somehow. At the moment, it's simple boxes and balls, just like Bryce.  I'll post a link to the video I am rendering now.
  I have to apologize, I know this is all very simple stuff to most of you, but I remember when I started with Rhino...  even the simple things were exciting, and new members brought it back every time.  My best Rhino model is posted here if anyone cares to look...  it's from a wood model plan. I created all the pieces, and built an antique car using Rhino instead of wood.
  OK, Time to check the render.  (And by the way, I know I sound like a ten year old, but truth is I am a grandfather of 6. I'm just having a good time tonight)
   Thank you for putting up with my excited ramblings.
