Machine pareidolia - exploring the tendency for humans to see faces in inanimate objects. (I'm curious - do people with faceblindness also recognise faces in inanimate objects?). Very nerdy. If you prefer the art version to the computer science version, please enjoy the Hello Little Fella! pool on Flickr. My favourite so far is this (though this, er, human brain has to be a close second).
I have a particular reason, even beyond loving Portal 2, for approving of the Perpetual Testing Initiative video. And yes, it HAS SUBTITLES.
I also have lots of political-type links that are anger-making, but my head hurts too much to want to inflict those on anyone else just now.
