Now here's some Friday afternoon hackery fun: Clever network admin Pete decided to mess with his wifi-piggybacking neighbors by flipping all the images they'd see on web pages upside down.

First he split up the IP addresses handed out on the network into a trusted half and an untrusted half. Then he sent traffic from the untrusted half through various scripts that flipped or blurred web site images, or redirected every web page request to the kittenwar.com site (ie, "kitten net.")
