These are links to a variety of examples of modeling and simulations.

Some of the models have explanations, some deserve more explanation, some
of the others I will try to talk about in the next couple of weeks . . .
The RePast "Wealth" model should run on your machine (modulo Java).
The NetLogo models can be run in a browser (again, Java),
and can also be downloaded so you can look at / modify / use (feel free
to borrow at will) the source code:

Here is a link to the "Non-Ergodic" model in NetLogo:

Here is a link to the "most different genome" model in NetLogo:
Most Different model

Here is a link to a "virus spread" and immunization model in NetLogo: virus spread

Here is a link to the "Sync" model (built in class):

Here is a link to the "slinky" model in NetLogo:

And, if you're interested, here is the Java source for the RePast model:
