Wifi Detector Tshirt
ThinkGeek has released a Wifi detector tshirt, which displays the 802.11b or g signal strength with glowing bars in front. The glowing bars in front dynamically changes based on the signal strength. You don’t have to open your laptop to check for wifi. The Tshirt is available in black only and it’s 100% cotton. It runs off 3 AAA batteries and the battery pack is concealed in a small pocket inside the shirt. The animated decal is removable for washing. Cool, eh!!!
