Commuters arriving at Liverpool's Lime Street station were greeted by a 50ft (15m) high mechanical spider clinging to a nearby redundant office block. It has been built by French company La Machine, which in 2006brought the streets of London to a standstill with the Sultan's Elephant. The spider is believed to be "waking up" on Friday. It will descend from its current position on the side of Concourse House on Thursday to be moved to the city's new arena, before coming to life on Friday. The creature will then begin exploring the city later that evening.
