DC Comics is carrying off a celebration of Batman Day to mark the 80th anniversary of the appearance of crimefighter Bruce Wayne and his masked identity.

Fan gatherings happened all over the world. But the most ambitious party plan was the illumination of the bat signal.

It started at Fed Square in Melbourne, Australia. It is also appearing in 13 other cities, including Tokyo, Berlin, Rome, Paris, London, Montreal, Sao Paulo and Johannesburg.

It's lighting up at the Domino Sugar Refinery in New York City before making its final appearance in Los Angeles at City Hall.
