The interface was designed using HTML5 and CSS3 on Windows Azure, with Python on Google AppEngine serving as the backend development platform, according to Katta's comments on Twitter. He revealed on Google+ that development of the unofficial app relied heavily on "a deep look at" Tesla's own Android-based app.
For those who happen to own both a Tesla Model S and Google Glass, the app can be installed directly from the GlassTesla website.
