I've just built a Solsylva CNC machine and am pretty new to all this. I've made a few basic things, but what I'd really like to make are some marble mazes for my kids (and their friends).

I was wondering if anyone here has experience with making mazes and what software you use to do so.

I guess I'm hoping for an easy solution to making mazes like the following:

I know I could start drawing in Inkscape or Illustrator, but I'm sure my efforts wouldn't come out as well as something automatically generated.
