T-Shirt Helps Find Hotspots
IDG News Service reports here at Yahoo News: The Wi-Fi Detector Shirt, which the online store ThinkGeek Inc. will sell for US$29.99, has glowing bars on the front that light up in waves when there’s an IEEE 802.11b or 802.11g network in range. As with a network strength indicator on a cell phone or PC, more bars light up as the signal gets stronger.
