|Hey who needs to carry around a WiFi detector when they can just wear one instead? For $30, you won't need the WiFi detector, you'll BE the WiFi detector. This T-Shirt has a animated, removable decal on the front that lights up when it finds a 802.11 b/g network and the bars on the side light up to indicated the signal strength. You wouldn't want to cover that up with a jacket, now would you?
Three AAA batteries used to power the shirt sit in hidden, sewn-in pockets. Even though the shirt is 100% cotton, you can wash it in warm water and not have your WiFi range shrink. The shirt is a different story.
