+Mr Doob (who I want to call Trace (: ) has a good page
+explaining how to do this and alternatives here:
+
+https://github.com/mrdoob/three.js/wiki/How-to-run-things-locally
+
+As you can see from that, as of right now (September 2016)
+if you're using Firefox, you should be EXTREMELY CAREFUL and be
+100% SURE YOU CHANGE THE SETTING BACK!
+
+** ESPECIALLY ON WINDOWS FOR CRYING OUT LOUD **
+
+Look if you're using Windows and Firefox to use this, and _YOU_
+don't set the setting back, YOU ARE GOING TO GET FUCKED.
+
+BECAUSE OF THIS:  I DO NOT RECCOMEND, OR SUPPORT, RUNNING THIS
+ON WINDOWS AND FIREFOX.  It works.  I do not RECCOMEND it or
+support it.  Someone is going to come back and fuck me over
+because of their stupidity and choice of OS.  Fuck that.
+
+I may be able to turn this into a chrome app at some point, which
+will eliminate that issue.  Possibly also a Firefox solution, but:
+As of today: I do not support this on Windows + Firefox.  That is
+100% at your own risk, because of the possibility you will forget
+to set the setting back.
+
+It's just plain safer to install this on your webserver at the
+party place in a directory and use _that._
