Here’s a link to a Java based Zombie Infection Simulator. I love this thing and immediately became addicted to it. I used to have a bunch of Mac based artificial life simulators and would leave them running overnight on my LC II every evening. Zombies and things like that are my most common form of nightmare. If I have a nightmare (which is rare) it is almost always about me being chased by something slow but inexorable. As I watch this goofy thing, I kind of feel for the little pink dots. I know what they are going through.
