The Wi-Fi detector shirt takes geek-wear to a whole new level. The image on the front of this shirt isn't static: The glowing bars light up according to how strong an 802.11b/g signal is when detected.
It requires a battery pack to work, and that's sewn inside the shirt. Three AAA batteries are required, so it will add to your weight a little.
But instead of looking really dumb walking around with an open laptop when searching for a hotspot, you can now look dumb by just looking at your own chest. And for those wondering, no, it doesn't tell you whether or not a hot spot is secured--cheapskate wardrivers will still need their notebooks to find their free fix.
