I've highlighted famous buildings, chairs, and paintings. How about a lamp this week. The Arco Floor Lamp, to be specific.
This lamp was designed by Italian brothers, Achille Castiglioni and Pier Giacomo Castiglioni in 1962, for Flos (an Italian lighting manufacturer). Their motto "design demands observation" caused them to see everyday objects in new ways. This particular lamp was inspired by the design of a streelight, and is designed to give overhead lighting without being suspended from the ceiling. It is balanced by a heavy marble base, which allows the lamp to extend 8 feet away- far enough to be centered over a dining table.
