The present invention provides a versatile construction kit that can be used to easily form models of virtually any conceivable person, place or thing including a variety of vehicles, buildings, people, animals, weapons, machinery, caricatures, objects and the like. The construction kit comprises plural disc-shaped connectors that are connectable by way of a tongue-and-recessed retainer mechanism and optionally also by way of interconnectable notches by which they can be perpendicularly and detachably interconnected and/or optionally by way of a tongue-in-slot mechanism. The universal connectors are so versatile they can form virtually any geometric, regular, irregular, asymmetric, or symmetric configuration.
