terra
JS library for cellular automata and simple biological simulations. Documentation and examples live here.
Hacking this library
To build terra on your machine you'll need Node.js, Bower, and gulp installed. Then...
cd path/to/terra
npm install
bower install
gulpContributing
At this stage the most important way you can help is to use the library. The API is in Beta and still flexible. If you discover something that's confusing or hard to work with, document it here. Come up with an idea and try to build it; by using and testing the library you'll find bugs or usability issues that would otherwise go unnoticed. If you want to make a pull-request on anything labeled 'major', be sure to join the discussion first so we can talk architecture. If anyone's willing to get the ball rolling on unit tests, you will be my hero.
That's all, folks! MIT, remixing strongly encouraged.
