Omniscience, meta-information, a digital sixth sense ... Would you like to be a techo-wizard yourself -- just pointing at stuff and commanding more information about it?  Even today, you can become a walking encyclopedia, just by cobbling together some cheap components and linking them to that cell phone in your pocket.  Pranav Mistry (a genius) has done this.  He can take pictures with his fingers, project information onto any surface (his palm becomes his keyboard), and find out more about anything and anyone that's in front of him.  It's called wearable technology, and they like to say it functions as your "sixth sense."  It's totally mobile, totally au naturel -- meaning you use "all natural gestures," no external hardware for astonished onlookers to see.

Watch the video ... geeks are getting awfully close to the brain implant!
