Think Geek has brought out a T-shirt so monstrous in its geekiness that it is ever so slightly appealing. The signal bars on the T-Shirt light up as signal strength increases. Obviously this thing takes batteries, three AAAs in fact. Apparently it will run for hours, displaying the strength of wireless b and g connections in your vicinity. Unfortunately, washing this thing sucks. The animated decal must be removed before washing, so it is not really a Wi-Fi detecting T-shirt. Rather, it is a flat Wi-Fi detector stuck to a T-shirt, but is a cool idea nevertheless.

Price: $29.99
