I find surprising that you seem to have put a lot effort into writing a comprehensive README.md and submitted to Hacker News and yet, there is no "easy to find" demo or screenshot. I suggest you immediately set up a demo on the gh-pages branch and link to it at the top of your README. Anyways, take this as friendly and in any case, thanks for publishing this.
Yeap you're right. Acually, you can simply clone the repo and open the examples in the browser. Nevertheless there has to be a demo page. I'll build one. Promise. And thanks for the feedback!
