Wi-Finding T-Shirt

Where's the wireless? Wear this and know instantly. The Wi-Fi Detector Shirt is a standard black cotton tee with one geeky distinction: a glowing decal that dynamically displays the current wi-fi signal strength. A discreet inside pocket holds a trio of AAA batteries that power hours of signal-detecting fun, and all of the electronic bits are removable come laundry time. We think $19.95 is a small price to pay for avoiding the disappointment of powering up a laptop only to find oneself marooned in a wireless dead zone. Plus, wearers are bound to make friends at the airport. Whether you'll be forced to power down the shirt until reaching cruising altitude is another story.
