Birthday

Part of a planar or spherical percolation front propagating from left to right. Red: an activated cell (the agent), black: inactive agents, green: susceptible sites, yellow: weakened site. Both, the susceptible sites and the weakened site, are attackable. In the next time step the agent is deactivated, and zero, one, two or three of the attackable places become agents. Note the asymmetry of the number of the attackable sites in the direction of the propagating front.
