Cloned project and ran the example project, but it keeps crashing Chrome and Safari? To prove that I wasn't insane I tried this on a few other computers. No luck.
What's weird is that it works fine in Firefox? Finally I commented out the kss.js and the example 'works' in Chrome, but that is not a real solution.
Have a look at #48, I'm pretty sure you're experiencing the same problem.
This has been fixed in recent merges. Thanks for the report.
