Torus: build Gilbert cells out of 2N3906 or 2N2222s, cheap as chips..
.. and perhaps you can time-multiplex a few using CMOS switches.
refurbish a lite-bright with an ATTINY for the EPIC WIN
better: who can build the smallest <random electronic gadget> on perfboard using only 1 layer for traces using DIP parts.
(might sound trivial, but once you're dealing with busses, it's becoming a struggle.)
