The exponentially decreasing signal to noise ratio in multibaryon correlators is the main obstacle to a first principles, QCD-based calculation of the nuclear force. Recently, we have proposed an orbifold boundary condition ("restless pions") that can dramatically improve this matter. Here we develop the idea further by proposing an explicit algorithm that can be used with purely periodic, "off the shelf" gauge configurations. We also discuss finite volume corrections with the new boundary conditions and the use of the "Luscher formula'' for the phase shifts.
