I love the guys at ThinkGeek just a leeetle more than is probably seemly. But it’s because they have grabbed the Geek Mindset with both hands and stuffed it into their mouths like so much Beefaroni, making chorfing sounds all the while. Their latest offering is the Wi-Fi T-shirt. The animated decal on the front (which is unpluggable and removable for washing) dynamically changes as the surrounding wi-fi signal strength fluctuates.

Yes, you could just crack open your laptop to check the strength. No, I don’t even want one of these shirts; I don’t own a laptop. But I love it anyway.

(Lawsey. They also have an umbrella that receives wireless updates from Accuweather and flashes a blue LED if rain is approaching. Shadow! I’m leaving you for the ThinkGeek team!)
