And you thought pocket protectors were geeky. In fact, the WiFi Detecting Ball Point is the perfect compliment to any gadget geeks lust for gear. Hit a button and the pen’s LED will light up if there is a WiFi hotspot in proximity. The greater the signal strength the more LED lights displayed; up to 4. Works with WiFi b/g only and won’t indicate if the network is locked, but it’s only $14.
