# The Ising Model: Colour to Break the Race

*Module of the free GPU.js GPGPU course · 6 tasks*

Metropolis on a lattice of spins, the race that makes an all-at-once update silently wrong, and the checkerboard that repairs it — ending in a temperature slider you can drag through a phase transition.
