Some ideas take “geek” to a whole new level, I swear.

ThinkGeekhas a new T-shirt out. Ah, this is no ordinary T-shirt, though. The WiFi Detector T-shirt, as its name suggests, includes a Wifi detector that will show the signal strength of local Wifi networks as you walk around. The T-shirt is powered by three AAA batteries, and ThinkGeek notes that it should :last for hours” before needing fresh batteries. Sizes range from small to extra-extra large, and the shirt will set you back $29.99. The shirt will be available later this month. With the Holiday shopping season approaching, this T-shirt might just make the perfect gift for the geek in your life.

Whatever you do, though, please do not try and wear this shirt on an airplane, lest you want the Transportation Safety Administration to think that you’re a terrorist, like this unfortunate soul.
