What's with everyone changing their profile pictures?

Has everyone got new phones or camera's?

Or has everyone suddenly gone all vain?

Yea, its a bit strange.... I assumed admin were updating something then noticed some of the changes are recurring.

Is it something we ought to be concerned about?
