Design Note #1: the Arbor Circle


An arbor is a small group of trees. I think of it as smaller than a forest, bigger than a grove. Ann Arbor (A2 to locals) loves its trees, and the co-founders of Ann Arbor named their new tree town after their wives, who shared a first name.

Like many of our designs, the Arbor Letter design has mathematical inspiration that has connections to nature. If you look carefully at the trees, you’ll note they are self-similar. Whenever a branch forms, the branch is a copy of the tree, reduced in scale. So the trees are fractals.

At first, we were taken with large (12”) diameter designs that we hung on the wall. But with a loop added, it makes a beautiful, delicate ornament. We make the design in a variety of sizes, and have written software for composing variations in the shape, positioning, and number of trees.
