/* if you're trying to embed this on your blog or website:
0. generate yr embed code as usual from https://moonconnection.com/moon_module.phtml
 - replace the js file path with this one
1. use https://rawgit.com to spoof headers
 - full url for this file is https://cdn.rawgit.com/isar0se/0c9c6580ee5097389a16aaa00e8c7673/raw/35dea55bce3955524d29d2024d7b6a06b4e32ce0/ccm_fl.js
 - if you try to past the raw file url in directly, the content type will be 'plain text' not 'javascript' or w/e
2. chrome disables flash autoplay by default & there's no way to un-disable it
 - the moon embed is annoying if there's a play button
 - but if you bump the embed width* to something like 700 at least (not sure the exact cutoff), chrome assumes it's content & not advertising & allows autoplay
 - autoplay is enabled via the '&autoPlay=true' param in the FlashVars string

/* can we do better ? definitely */
