San Francisco problem solver Steve Hoefer created an ingenious Rock Paper Scissors Playing Glove that competes against whoever is wearing it. Over time it adapts to how the wearer plays and then works against their weaknesses.
It remembers how you play so that if you always open with Rock it will tend to open with Paper. And if you tend throw a Paper after a Rock it will counter it with Scissors. The glove’s current record for best-of-five matches against me is 71 wins and 62 losses.
