That smoking spy icon in Ritchie's screenshot gives me flashbacks to mid-90s childhood. I remember seeing it around quite a bit for a while, but can't remember where. Anyone know where it's from?

It is a face, aka picon. It reminds me of the GameSpy logo. It appears to be the default face for unknown.

Info about faces in Plan 9: http://plan9.bell-labs.com/wiki/plan9/Adding_your_face/index... doesn't seem to load but is cached is http://webcache.googleusercontent.com/search?q=cache:CkBURro...
