Right now, Google Glass is just a pair of weird looking specs that's pretty much only used to take blurry photos and Instagram selfies. And that's okay! The real promise is what comes next. Developers have been getting their hands on Google Glass and have begun to see what they can build with it. It's the base for the future.
Playground Inc. imagined what Google Glass would look like in the future. Not today's Explorer edition, but a concept of what it can be in a few years when wide ranging apps have been developed to take advantage of Glass' unique technology. It's not unlike comparing the iPhone today to what it first was way back in 2007 (a third party app-less phone that just showed you basic stuff like your calendar, the weather, photos, notes, etc.).
