Described herein is an apparatus having first and second housings and a driver wheel. The first and second housings are coupled together so that they can be driven by the driver wheel to provide for a plurality of apparatus configurations. The apparatus is configured such that the first and second housings are slidable relative to one another from a first overlapping configuration, in which the first and second housings are substantially overlapping, to a second laterally slid configuration in which the first second housings are laterally slid with respect to one another, and then onto a third tilted configuration in which the first and second housings are tilted relative to one another. The apparatus is also configured such that continuous rotation of the driver wheel drives the movement of the apparatus from the first configuration to the second configuration and then onto the third configuration.
