Starting with Rhino

I had been waiting till I got a monitor to start learning Rhino and I finally got one Tuesday.  I got a used 24 inch monitor pretty cheap.  It's so much better to use CAD software on a big monitor.  So I'm working through basic tutorials now.  I'm going to try to stick with it till I learn it well this time.  I was learning Matrix several years ago, but got bored with it and never learned it that well.
