This site contains pictures and movies of computer simulations of certain spatial branching models. These models are

1. Catalytic Branching Random Walk in dimension 1
   • Without drift
   • The reactant has a drift, the catalyst has no drift
   • The reactant has a drift, the reactant stands still
   
   
2. Catalytic Branching Random Walk in dimension 2
   
   
3. Mutual Catalytic Branching Random Walk in dimension 2
