20 - tyFlow Creating a Marble Run Part 1

I have had a few requests about the process of making a marble run in tyFlow. This starting tutorial talks about track design, what works and why. Then, we make our first couple of modular track segments. It is meant to get someone going on making their own marble run, but it needs several parts to cover prettying things up, making cool gadgets to influence how the marbles run. I expect it to be a 3 to 4 part series. Enjoy.
