Of all the dumb uses of good technology I can think of, this one takes the cake. Guys at Monash University in down under have created technology that makes it possible for people to log on to their computers by simply laughing. One of the uses mentioned is "the system could be used to follow an executive as they walked through an office, ensuring that their email was always available on the nearest computer". Boy, I surely wouldn't want my email to appear on every computer I pass. Imagine people in cubicles tearing out their hair everytime someone cracked a joke and got logged on to every computer, hehe..And what if I am feeling grumpy?
