What's with these new-fangled devices using _electricity_ anyway? :-)

In high school, my math teacher (I think it was) used a couple of matchboxes
and some beads to create a TTT device; he 'programmed' it by playing against
it, and when the device lost a game, he pulled out the bead that indicated
the device's previous move, so it could never make that losing move again.
Pretty impressive, I thought...
