Wi-Fi detecting t-shirt

This t-shirt helps you to find WiFi hot-spots as well as their signal strength. Cool eh ? :D

But the downside of wearing this is that, everybody gets to know that you have some sought of a valuable laptop or phone with you. So be aware. ;)

If you want to, you can buy it here -
