There are lots of potential applications. To start things off, Google lists cooking, cycling, skiing, golf, and firefighting — physical activities where holding a device is impractical if not impossible. But really, it was only a matter of time before people began using it for sex.

The first attempt, an app called Tits and Glass, allowed Glass users to stream pornographic images to their headset. The app was promptly banned from Google's app store, but was recently reinstated.

Now a new app for Glass developed by Lebanese product design student Sherif Maktabi and called Sex with Google Glass lets couples use the wearable technology to record their intimate activities, and — if both partners are wearing a headset — even see sex through their partner's eyes by streaming the view from their respective devices.
