There is arguably no possible pattern of speciation that has not already been discovered by the branches of a tree in the wild, or planted in some park, or along some city street. I'm interested in recording some of these patterns, not necessarily as the start of any visual narrative, but as a self-contained metaphor for branching narrative, for the split and sweep of multiple possible futures. By examining a single tree, I can contemplate a dozen possible approaches in as many minutes.
