Probably about as long as I've been using Wikipedia I've wondered what the dull grey image in the background at the top of the monobook skin is supposed to be. You can only glimpse part of it, and if you're using a smallish monitor, that's a very small part indeed.
Well, today I suddenly glimpsed enough to see it for what it is. Wow.
For anyone who hasn't worked it out, I won't spoil it. :)
PS Am I the only one for whom the words "log out" appear over a dark grey Africa-shaped blob?
