It's strange where inspiration comes from, how we stumble on the stuff we need as long as our eyes are open and our minds not distracted at the time. I was helping Ingrid edit an essay she had written for her art homework. The essay was about a model she had made for a useless building. The building was a clear sphere in a tree. Anyway, I began look at strange, amazing tree hows and I rediscovered the concept of follies.
