Wi-Fi Detecting T-Shirt lets you know when you're in a Wi-Fi zone by graphically displaying the Wi-Fi connections floating around the vicinity. Glowing bars on the front of the shirt dynamically change as the signal strength fluctuates.

Capable of showing strengths of 802.11b or 802.11g, the Wi-Fi Detecting T-Shirt is destined to become an essential traveling companion for all.

This is a t-shirt for internet maniacs

The animated t-shirts are great. I would like to have one.
