The cool technology of the week, is the Wi-Fi Shirt from ThinkGeek.com.
This shirt includes an embedded wi-fi receiver, miniature battery pack and a detachable illuminated display that shows wi-fi strength in real time.
This is clearly the must have fashion for network engineers and frequent fliers.
As to the claims on the website that it will attract the opposite sex in wireless cafes, I'm dubious. As a happily married man, I do not think about such things. And besides, my pickup lines such as "I'm a Harvard faculty member and CIO" would never impress the cafe crowd.
