A simulation framework is described in which sliding tiles moving in a discrete two-dimensional grid can be put together to build machines. The tiles can perform logical and mechanical functions, and can be connected to each other. A self-replicating machine has been designed in this environment and its operation is summarised. Observations are made about the usefulness and the limitations of the machine and its environment, and several ways in which the limitations could be addressed are described. A justification of the simulation approach for modelling self-replicating systems is given.
