Query: Xtoys: cellular automata on xwindows   Xtoys is a collection of xwindow programs for demonstrating simulations of
various statistical models. Included are xising, for the two dimensional Ising
model, xpotts, for the $q$-state Potts model, xautomalab, for a fairly general
class of totalistic cellular automata, xsand, for the Bak-Tang-Wiesenfield
model of self organized criticality, and xfires, a simple forest fire
simulation. The programs should compile on any machine supporting xwindows.
