A stackable full adder built out of discrete CMOS pairs, with LEDs on each transistor's input and a flip flop on each drain (just one flip flop if multiple transistors have a common drain). This allows visualizing the effect that propagation delay has on an adder's speed. Components are generally rather small to save on PCB space and production costs, but are still hand-solderable.
