The companion video to Tech Blog 200--this one on how to find hybrid families using QFT (poi) notation. I highly recommend watching this in 720 and full screen so you can see all the numbers on the whiteboard. For some background, I highly recommend checking out my blog entry on the basics of QFT here:

QFT does a really excellent job of showing the mathematical patterns of particular moves. Because of this, when we see a certain patterns of numbers repeating between patterns, it tells us there is a simple transition that exists between the two. Here is one such example, but there are many, many more to be found! Here is the QFT for the moves outlined in this video:
Key: Hand depart, poi depart, poi direction at depart point, handpath radius, hand arrive, poi arrive, poi direction at arrival point
