With Glass set to be the best big thing, it would make sense that the second biggest social network in the world begin testing their application for the wearable eyewear from Google.
Google have been using the hashtag "#throughglass" on their Google+ posts using their Glass hardware, and earlier in the week we had Twilio developer Jon Gottfried hacking his own Twitter Glass application using Google's Glass API. He also used that same hashtag for tweets sent through his app, GlassTweet.
The developer also noticed some other tweets showing up with the #throughglass hashtag, but these tweets had an official "Twitter for Glass" label on them. If you're a developer, you can't just slap "Twitter" on any tweet, as the social network restricts the creation of apps with "Twitter" in the name. So this might actually be the real deal.
