What are these strange signs on London Underground?

You may have seen these strange signs on London Underground and wondered about their purpose etc.
When I saw one such sign very first time I thought it looked like a tube map for aliens...
But in reality these signs are Labyrinth art project by Mark Wallinger to mark 150th anniversary of the London Underground.
More information about Labyrinth art project can be found on TFL website.
