I came across an article online about Ubuntu machines being spotted on the set of Doctor Who, a famous BBC show that I personally grew up with.  Apparently, according to Popey, the accompanying show was showing the making of the episodes in question.  The displays of the computers show what seems to be Ubuntu splash screens.  I just zoomed the accompanying pic.  While I can't tell the version, I would recognize an Ubuntu screen anywhere.  I hope Mark Shuttleworth knows how much of an honor it is to be the chosen OS of such a phenomenon as Doctor Who!
