Just what everyone needs: Instant notification when there's Wi-Fi available while you're driving.
Now you can just whip out your laptop whenever you see this bumper sticker, provided there's enough signal strength for you to start surfing right away!
Instructables shows you how to create such a scenario, a lot simpler than it looks because all you need to do is grab one of those Wi-Fi T-shirts, carefully cut out its electroluminescent panel, and stick it onto the back of your vehicle. Why you would do such a thing? Because it's cool!
