Battery pack

I was thinking the same thing, I'd get one just for fun, as I have 40 or so ball caps now, whats one more?

Great concept, but I think it'd work better packaged in a ball cap. For extra geekiness, add solar panels to the bill.

Or build it into a necktie. The greater the signal, the more lines. Full signal strength illuminates the entire length of the tie, from knot to point.

Either would be loads of fun until the cool kids beat you up.

Before I would wear anything like this. Someone actually said it was cool. No, its not. Interesting, sure. Its the kind of shirt you might wear if you are working at a booth at at technology fair, and your product involves WiFi. That is probably the only safe place to wear it.
