We’re all pretty aware what Google’s Glass project is capable of at this point, and those lucky few who already have their hands on the device have been kind of enough to rub it in our faces. But it looks like those online videos and official spec sheets haven’t quite revealed everything Glass is capable of.

One particular bar in Seattle won’t be too pleased when they find out that a user on Reddit has dug up an interesting little feature that hasn’t been put to use just yet. The code references “eye gestures” for Google Glass to take advantage of, more specifically, to take pictures — with a wink.

To avoid the device taking pictures every second (we humans need to blink pretty often), it looks like you’ll be able to calibrate when this gesture will trigger a shot. This is a much more subtle way of taking pictures when compared to saying, “Okay Glass, take a picture” every single time. But why Google hasn’t made use of this existing code, let alone mention it, remains unknown. Perhaps they could be waiting for all the privacy issues concerning Glass to die down, because it’s already pretty bad as it is and an even stealthier way to take pictures isn’t going to make things any better on that front.

But for now, watch out. Taking creepy photos of that attractive individual is going to get a lot easier when or if this feature ever rolls around — or it could get weirder, since you’ll be winking at the person.
