Monte-Carlo simulations of spins dynamics in the XY magnetic model.
Similar to the Ising model spins with different orientation φ
are painted in different colors Hue(φ/2π).
Vortices and anti-vortices correspond to
the singular points (defects) where all colors meet together.
For T = 0.03 "hot" (random) spins are frozen in correlated clusters.
You can watch vortices and anti-vortices formation and annihilation.
Set in the T field T = 0.003 to freez spins.
