After reading "The Juggler's Brain" by Nicholas Carr, I saw this post at Kottke.org (http://kottke.org/12/04/google-glasses) about what Google Goggles would really be like. Here are two great videos about what real life might be like with "Google Goggles." I especially enjoyed the second one, which seems to fall inline with our more "dormant pre-frontal cortex" (p. 121).
You can check out the NYT article on Google's "Project Glass" here. Because those are some sexy glasses. (Don't worry, they also come in contacts!)
