Optical Illusion of the Day: To promote the “psychologically and physically thrilling” Nemesis Sub-Terra ride set to open next month at Alton Towers Resort, artist Andrew Walker was commissioned to design an equally psychologically and physically thrilling 3D illusion for an elevator at the Southside Shopping Centre in the south London district of Wandsworth.

“When creating the illusion inside the lift we considered some our most common fears including heights, darkness and claustrophobia that are also a core part of the new attraction,” said Alton Towers spokeswoman Katherine Duckworth. “The reactions of the public were fascinating and we can’t wait to see what happens when people come and experience the new attraction for the first time.”
