2012 Global Dart hackathon #darthack
To work with this code get started with the Dart Editor http://www.dartlang.org/docs/editor/getting-started/
If you're feeling adventurous you might try the eclipse plugin (I never did get this going though).
To run the code from Dart Editor, open the folder at the root of the project, right click on meanderthal.dart (it's down near the bottom) and choose Open in Dartium.
