Escaping from Zombies - Visualized (in R! Really!)

Francis Smart, over at Econometrics by Simulation, has the first (and quite possibly, only) R-based simulation of how one can escape from zombies.
From the post

# Escape Zombie Land!# This is a simulation an escape from a hot zombie zone.  It freezes and gives an error if you get get killed so you had best not.  To play it you attempt to navigate the zone by constructing waypoints.

It is remarkably configurable, (you can set the number of zombies, their acceleration, waypoints, and pretty much everything else.  Most importantly, you can generate really cool animated GIFs like the above.
Go check it out, its worth the time :-)
