Disclosed is a wall system employing one or more stackable connectors that are capable of engaging one with another independent of fasteners and being mountable to a respective wall panel. In one embodiment, the system includes: a background sound generator, a mixer coupled to the background sound generator and a user interface, coupled to the mixer, that, upon a user command, causes the mixer to mix an output of the background sound generator with a transmitted signal. The bottom of the pot has a unique structure including a central hub and a plurality of radially extending stand-offs extending outwardly therefrom to the periphery of the bottom wall. The lighting structure of the present invention can be assembled with a light cover. The electrical signals are then evaluated with an evaluating device, wherein the movement of a seat belt webbing influenced by the body of the belted-in vehicle occupant is scanned and a corresponding signal is fed to the evaluating device.
