About a year and half (!) ago, I started playing with this idea of Links and Chains. Maija, always insightful, asked the reasonable question "what is this for", and I discovered I didn't really have a great answer. I played with a couple of things in classes, but it really didn't seem particularly useful, so I shelved it.
Recently, though, I did a couple of seminars where people started asking about building combinations, and I found that I was going back to this model. I didn't bother with all the terminology, but the idea was there. It seemed to click. It'd be interesting to run a full seminar on it and see how much people could do with it on their own.
Maybe it's got a place after all.
