I just released Winky, a way to take pictures with a wink on Google glass. This was a fun project that involved a bit of decompiling of GlassHome to see what was going on. I discovered a few other interesting tidbits that I'll be looking into as I get time. The hard work related to Winking was done by Google engineers, I just did the hard work of exposing that to the rest of the world.
Winking really changes things. You might not think it's hard to say "Ok, Glass Take a Picture" or even just tap a button. But it's a context switch that takes you out of the moment, even if just for a second. Winking lets you lifelog with little to no effort. I've taken more pictures today than I have the past 5 days thanks to this. Sure, they are mostly silly, but my timeline has now truly become a timeline of where I've been.
The big technical hurdle turned out to simply be that at least one spot on Glass does some checking against the build type and disables the wink gesture completely if it's a user build and it ever detects a wink. I was able to get around this by intercepting the wink with a higher priority than anything else.
To provide a little more clarity, this is being released as pure Android source code. It's intended to be compiled and run as an APK. At this point, I'm figuring most of you guys with Glass know how to do thisI'm trying to stay away from providing just APKs since there may be personal information that is less protected than on your average Android device and I don't want there to be any questions about whether I'm touching your data or how much work I've actually done. It isn't much. This is different from the typical Glassware that the NY Times or Path provide.

Sorry for the terrible layout. You should only ever see this screen once anyway. So here's the UI https://plus.google.com/photos/116031914637788986927/albums/5872857971460704145/5873222037894808786?banner=pwa+Chris Davies +Derek Ross +Rob Jackson +Jenny Murphy
