Simulate the HPP lattice gas model. Take as a starting condition a randomly seeded lattice, but completely fill a square region in the center and observe how it evolves. Use periodic boundary conditions. Now repeat the calculation, but leave the lattice empty outside of the central filled square.

Simulate the FHP model, with the same conditions as the previous model, and describe the difference. Alternate between the two possible two-body rules on alternate site updates.
