Stealthy? Have you actually seen somebody wearing glass? It's the most noticeable thing about them. During IO there were a bunch of Glass wearers wandering around Moscone and people couldn't stop staring (myself included).

You'd be much better off with something like this: http://www.amazon.com/Waterproof-Camera-Watch-Video-Recorder....

Sure, everyone can see they’re wearing glasses. However, outside of our little tech circle, most people don’t know that those glasses contain a camera, mic, and location tracker. And even if a Glass-wearer gets called out, they can deny that they were recording or taking pictures (unlike if you point a camera watch at someone).

You could do much better by getting rid of the HUD entirely and embedding just a camera lens/sensor, which can be really small, into some normal glasses ... for spy pictures you don't need perfect composition ... 😓
