Animated WiFi detector shirt keeps you single with signal

Life's great priorities -- human interaction and network access -- seem to exist in perpetual tension, but those of you who know exactly where you stand might want to check out this Wifi Detector shirt, which will simultaneously inform passerby that a WiFi network is nearby and that they probably don't need to speak to you. The detachable detector / display combo runs off three AAA batteries for "hours" -- just long enough for you to alienate the locals before heading back to your parents' basement. Scarily enough, it's already out of stock, but ThinkGeek should have more in a couple weeks for $30.
