There’s nothing like combining tee-shirts and technology! There are some brilliant tee-shirt designs out there, and the sky’s the limit for innovation. Here’s a design that incorporates an actual Wi-fi detector. For anyone who’s ever walked all over the city with a laptop or ipad, looking for wi-fi access, this is a great idea…..If you wear your trusty wi-fi detector shirt next time you go out, it will display all the wi-fi hotspots, and give the signal strength! The glowing bars on the front of the shirt dynamically change as the surrounding wi-fi signal strength fluctuates.
