This final note today, in which Google's quest to take over the world moves another step forward.
I direct you now to the U.S. Patent and Trademark Office -- specifically patent number 8,510,166, issued 10 days ago for a "Gaze Tracking System."
Or, to paraphrase, Google Glass is gonna be watching you while you're watching it.
And then how about this, buried deep down in the fine print: A pay-per-gaze advertising system.
The thing's gonna measure pupil dilation so see how invested you are in the ad.
