Wouldn't I need a node.js server to run that? It's listed as a prerequisite in the GitHub page...
I've not worked with it except as an end user. But my understanding is that you only need node.js if you're trying to test this locally, because browsers treat file:/// URLs differently than http://localhost
You are right, actually, as long as it's coming from a webserver (IIS here) I'm able to run the demo. Thanks!
