Lizard Scale Patterns Described with Antiferromagnetic Model The pattern of green and black scales on an ocellated lizard can be described with the two-parameter Ising model for antiferromagnetic systems.

Lizards are surely among crystallographers' fave pets together with photonic-crystal beetles and forever-twinned sea urchins... but for #DiffuseScattering & #CorrelatedDisorder nerds nothing beats lizards... 🥇💯 physics.aps.org/articles/v15...
