     XTOYS
          xtoys - Cellular automaton and wave equation simulators for X.

     SYNOPSIS
          xising
          xpotts
          xautomalab
          xsand
          xfires
          xwaves
          schrodinger

     DESCRIPTION
          xising: implements a simulation of the two dimensional Ising model
          with both local and cluster algorithms.

          xpotts: for the q state Potts with a magnetic field.

          xautomalab: a totalistic cellular automaton simulator.

          xsand: implements the Bak, Tang, Wiesenfeld sandpile model,
          illustrating self-organized criticality.

          xfires: a simple forest fire model of self-organized critiality.

          xwaves: simulates three different wave equations, representing light,
          massive mesons, and water.

          scrodinger: evolves a wave function with the Schrodinger equation.
          The potential can be modified with the mouse.

     OPTIONS
          No command line options are implemented.
