Neat new program

In my searchings for a Landscape CAD program, I ran across several lame ones, and another, that is more of a 3d Sketching software that is capable of producing Cell shaded renderings. I'm currently learning it to create a 3d version of the new landscaping. Its called SketchUp, and it is written in Ruby uses Ruby scripting for animations. I only mention that because my cousin's boyfriend Thomas has talked about an interest in Ruby on Rails. I think just the name sounds cool as hell, like some kind of Bose - Einstein condensate laser cooled mag-lev or something, but what do I know.
