Patterson, a subtle parody of the contemporary map design, first displayed in 1992 in which the station names on the Tube map have been replaced by those of famous figures. In 2003, to coincide with the publication of a book about tube maps from all over the world, the London Transport Museum released a "World Metro Map" poster that was strongly based on the London diagram and approved by TfL. Animals on the Underground is a collection of over 20 animal characters depicted using only lines, stations and interchange symbols on the London Underground map, created by illustrator Paul Middlewick in 1987. In 2003, the concept was used in a poster campaign by advertising agency McCann-Erickson to promote the London Zoo. In May 2010, a children's storybook was released that used the characters, "Lost Property". It is the story of an elephant called "Elephant & Castle" who loses his memory and is helped by Angel the angel fish. The book was illustrated by Middlewick and written by Jon Sayers, and its official launch took place at the London Transport Museum. Albus Dumbledore, a central character in the Harry Potter series, has a scar just above his left knee that is in the shape of a Tube map. In 2006, The Guardian published a design based on the tube map, purporting to show the relationships between musicians and musical genres in the 20th century. On 11 January 2007, Lord Adonis unveiled a depiction of the map featuring the names of successful schools and students at GCSE level as part of the London Student Awards 2007. The Royal Shakespeare Company produced a map in 2007 linking Shakespearean characters according to their traits in a diagram that resembles the map for complexity. The game development studio Dinosaur Polo Club created the game Mini Metro, whose main mechanic is to efficiently connect stations in a strict Harry Beck style. Stylistic aspects of the London diagram, such as the line colours and styles and the station ticks or interchange symbols, are also frequently used in advertising.
