    Abstract: A new model for mechanical computing is demonstrated
    that requires only two basic parts: links and rotary joints.
    These basic parts are combined into two main higher level
    structures: locks and balances, which suffice to create all
    necessary combinatorial and sequential logic required for a
    Turing-complete computational system. While working systems have
    yet to be implemented using this new approach, the mechanical
    simplicity of the systems described may lend themselves better
    to, e.g., microfabrication, than previous mechanical computing
    designs. Additionally, simulations indicate that if
    molecular-scale implementations could be realized, they would be
    far more energy-efficient than conventional electronic computers.
