Wi-Fi Detector T-Shirt
Our bonus T-shirt is the ever-popular Wi-Fi Detector (which also appears in our otherwise nonoverlapping slideshow "[[xref:http://www.pcworld.com/article/171412/15_tech_tshirts_we_love.html|15 Tech T-Shirts We Love|15 Tech T-Shirts We Love]]," from last year). This garment actually lights up when it detects a Wi-Fi network. The stronger the signal is, the more bars on the shirt light up.
