Lately, I have been watching a lot of Ghost in the Shell: SAC.  In the show, the main antagonist is a Salinger-loving uber-hacker who has a tendency to replace faces in live video with his rotating-text logo.  As with many of my projects, this piqued my interest, and sent me off coding.  So, here to all of you, I debut the first version of my little python script, Warai, for replacing faces with logos.  Hopefully I will add support for video in the future.
