Want to be a walking Wi-Fi detector? The Wi-Fi Detector Shirt ($19.99) has a basestation design on its front with signal waves emanating from it that glow according to the intensity of a nearby network's strength. For example, a weak signal may only light up a couple of bars on your shirt, while a stronger signal could illuminate all of them.
The shirt is works with 802.11b/g and runs on three AAA batteries that sit inside a small pocket sewn into the shirt. And if you're a messy surfer, the Wi-Fi decal can be removed so the t-shirt can be washed of course.
