Apple have taken a step into the world of architecture with their latest patent – an all-glass spiral staircase wrapped around a cylinder. They have patented the design, method of construction and materials used for the staircase, which leads patrons up to their Shanghai store.
Apple also tried to trademark the design of their store in New York City, which from the outside just looks like a big glass cube, but once inside it leads shoppers to an underground iStore.
