Look at the size of my Wi-Fi

ThinkGeek is selling a Wi-Fi Detector shirt that picks up wireless networking signals and displays glowing bars on the shirt which also depict the signal strength. Now, while I'm not sure if the T-shirt thing is going to take off, I think this is a pretty cool, and extremely geeky idea. You don't have to wonder if there's wifi in the area... just check out the shirt.
