Factory Town by Erik Asmussen

Build, Expand, Automate, and Optimize your own fantasy village in the wilderness using marble-run chutes, railways, running water, magic currents, and conveyor belts.
Or, build a log-powered mechanical calculator using logic switches, physical gates, and detectors.
Factory Town is Town Builder/Factory Simulation where you guide a wide array of construction and consumer goods through production chains, trying to maximize efficiency and output while keeping your townfolk happy.
