I remember watching "The Price is Right" as a kid, and seeing a Planko type game where the contestant releases a round puck at the top of the board that then bounces off of metal pegs to land at a number down below.

A sort of simplistic neural network could be made by varying the charges until the puck landed at the desired position.
