Rock-Paper-Scissors-Lizard-Spock Scale

This CAD model was designed by Oskar van Deventer, copyright (c), 17 November 2024.

Rock-Paper-Scissors-Lizard-Spock Scale was commissioned by Claire Postlethwaite, professor on "networks of intransitive competition", see https://sites.google.com/view/clairepostlethwaite . Claire asked me for a mechanical implementation of Rock-Paper-Scissors-Lizard-Spock, a game invented by Sam Kass and popularised by The Big Bang Theory. The implementation is a scale with five pans and ten levers, one lever for each pair of pans. The scale is non transitive. Wherever one weight is placed, there are always two other pans where the other weight would "win", by tipping the scale.
