RFID + Dart gun = DartMail!
breon.halling writes "Snail mail? Too slow. Email? Too much spam. So what's left? DartMail! Tony Tang and Eric Pattison from the University of Calgary introduce a new (well, new as of January 2003) method of transferring files and possibly shooting your eye out. Using RFID and a toy dart gun, 'DartMail lets people physically shoot electronic information at others.' Be sure to check out the movie, too!"
I'd be more interested in seeing something that would let you shoot a specific bit of information wirelessly at specific people near you. Seems like it'd be a funny way (now and then) to get to know people, by sending weird little one-liners to them from across a room. Among other possible "silent-communication" possibilities.
We are one consciousness experiencing itself subjectively. Back to you with the weather, Bob!
