Google has unveiled the first video taken with its sci-fi eyewear concept, Project Glass. The topic: jumping and flipping on a trampoline, doing a backflip while wearing Google glasses.

Google launched its Project Glass goggles on Google+ in April, and the news sent the concept of Google's futuristic glasses — which would project augmented reality images into wearers’ field of vision — into a worldwide frenzy on the web. Although Google co-founder Sergey Brin has been testing the device and teasing pictures to show the Internet what it can do, this is the first time we've seen a video taken by the device itself.

In addition to taking pictures and video, the glasses can perform many tasks performed by a smartphone. For example, while wearing the glasses, you would be able to see weather forecasts and what's on your calendar for the day, as well as send text messages and emails to friends and family — all projected right before your eyes.

Google told Mashable in April that selling the glasses this year would be "very unlikely."
