The Stag Hunt, Bath, October 2019

If you squint, the relative sizes and positions of the stag and the hare in this tableau evoke the relative expected utilities of the two Nash equilibria in the coordination game — the low-utility (“risk-dominant”) equilibrium of uniform defection (“Everyone hunts hare”) and the high-utility equilibrium of cooperation (“Everyone hunts the stag”).

I have no idea what role the puffin plays in all this.
