Monte-Carlo simulations of the phase transition in the q = 3
Potts model a generalization of the Ising model.
Just the same thermostat algorithm, chess-board order,
linear congruential random numbers are used.
Spins (magnets) take 3 values marked by the red, green, blue pixels.
Interection energy is 1 if two spins have the same direction
and 0 otherwise.
It is likely that magnetic phase transition takes place at Tc = 1.
Temperature T = 0.9 < Tc is low therefore "hot" (random) spins
are frozen in correlated clusters.
Drag "thermometer" to the right to change T.
