I met with Jay Lincoln, a local artist and teacher at a coffee shop. He drew sketches for me and we worked on it. It was during this meeting that the project fully became collaborative.
Jay suggested adding outriggers to hold up the long spans of the branches—perhaps to appear like ladders, or if the branches touched the ground. I insisted the branches be free-standing, though … unless, of course, it proves impossible to do so. He had the idea of integrating ladders and stairs into the minor branches which would be fine by me.
