I built a somewhat similar framework a year ago [WebFUI](https://github.com/drcode/webfui) aimed at ClojureScript. My framework also uses global event delegates, a global "render" function, DOM reconciliation, etc just like react.js. (Of course these ideas all have been floating around the ether for ages, always great to see more people building on them.)
