One of the problems associated with improving your wireless equipment (better NICs, higher gain antennas) is that your detection range improves and you're more likely to see "odd" stuff. Case in point: the following two screenshots were made about 12 hours apart. Can you tell what my neighbor's kid got for Christmas and can you tell why his dad might get upset? (Note: this is not a contest. It's just silly.)
Answers: it looks like the kid received a Nintendo and it looks like it was on all night.
