Vector spin model

This is a molecular dynamics simulation of an array of magnets (or "spins") free to rotate about fixed lattice sites. Gradually changing the temperature and/or modifying the applied field produces interesting ordering effects.

Available user controls are a start/stop button, sliders for choosing the temperature, field, the number of timesteps between display updates and the array size, and a button for specifying whether the interaction between spins is ferro- or antiferromagnetic.
