This is a demo of Ra for SPLASH and Carleton Data Day. If you're using Firefox, try out this maze.
There is a Chrome-compatible version, but you
have to start the browser with a command like
--js-flags=--harmony_proxies (substitute the appropriate binary name).
Proxy feature is recently standardized, V8 only
implements an old draft, so the entire feature is turned off by default.
I didn't test any other browsers. It's prototype software anyway.
