This is a collection of html5 javascript simulations (and a couple of visual python models too). Click on the drop down menu to see some of the examples that I've been using in my classes to supplement homeworks.
Here's a social force model that my students in computational biology developed for a zombie apocalypse in John Jay (science and engineering builing at RMU). That code is a little too big for here, but we used a simpler model for testing parameters and debugging which I'll embed below. The zombies are green (naturally) and dead people are red. Closed doors are blue (but some people can open them) and open doors are transparent. Zombies can infect people (dark green with an average incubation period of 10 s) and people can fight back and kill the zombies. Click Run and see what happens!
