After a neighbor started stealing Pete’s wifi bandwidth, he decided to have a little fun. To give you some idea of the mayhem he caused, he:

  1. Sent all website traffic to the kittenwar website
  2. Flipped all of the images and text on the websites the neighbor was visiting, so that they were upside down
  3. and mogrified the images to appear blurry

Out-freakin’-standing.  Go here and learn how he did it using iptables and a few mogrifications.
