Walking along the south bank of the Thames near the London Eye, I caught this juxtaposition of the Tower Clock in the houses of Parliament and a Dali sculpture, "The Persistence of Memory." (I'm not sure whether Dali did the sculpture or whether it is based on his paintings; I know more about Renaissance art than 20th-century art.)

Pedantic note: the Tower Clock is not Big Ben. Big Ben is the large bell in the tower.
