Under encouragement from the City of Cambridge's Department of Transportation, we created an urban fractal-inspired "tree" as an artistic bus stop installation. The overall purpose is to illuminate the environmental benefit of riding the bus, rather than riding in a car. The installation, designed from the essence of what we consider an urban tree to be, grows and dies in response to the number of passengers waiting for the bus (the more people there are, the more alive the tree is; and vice versa). We used an ultrasonic range finder (distance sensor) in tandem with a stepper motor and pulley system to activate the tree. The branches, reminiscent of natural fractals such as ferns, were constructed out of segmented triangular prisms, connected with nylon. The trunk acted as a base for the project and storage space for the sensors.
