If you have WiFi, it can often be difficult to find the right spot. But some mighty clever folks have designed a glowing, animated shirt that changes bar strength for the wireless signals. The clothing works for both 802.11b and 802.11g connections and runs on a battery pack concealed in an inside pocket. The decal is attached by hook and loop fasteners so that you can remove it to wash the shirt. It will work for several hours on three AAA batteries (not included.) The black t-shirt is available at ThinkGeek for $29.99.
