Anyone know if one is available for this machine?
Not through the amazon App Store. It'd probably take a bit of time but google how to run android apps on the kindle fire and you can get it on there
The Kindle Fire is an Andorid tablet with Amazon's skin and restrictions on it; which is why you can't access the Play Market. If you know how to, and are comfortable with side loading apps (http://features.en.softonic.com/how-to-side-load-apps-on-the-kindle-fire) email me at email@example.com and I'll email you the .apk file.
That being said, my advice is to root the tablet, and turn it into a pure android device, and not one with restrictions.
Or, if you trust me (and I claim to be extremely trustworthy), you can use my web-based app at http://artspeak.quogic.com/teslalogin/html
Dozens of people are using it and so far I haven't carjacked anyone.
