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!"
As opposed to posting on Slashdot bitching about how someone else spends their time? ;)
Do you actually have to ask? This IS "news for nerds", remember... If you can't see the appeal in having an excuse to combine geeky electronics + launching ballistic projectiles at "friends", then maybe you're on the wrong forum...
