There is a plan for a lengthier explanation video.
The intention of the video was to show that it can be done. Of course, some kind of explanation and training is needed for everything, I don't dispute that.
My problem with the video is that it doesn't show me what can be done. It shows me that the ball can follow the line and with some magical symbols and lines "other logic" can be "somehow" added. It didn't do anything to tell me what other logic is possible, nor did it explain what the symbols and lines mean. So I still don't really know _what_ can be done (besides a pong game) and I've no idea what most of the on screen stuff even is or means.
