Frisbi hanging lamp, 1978 Steel, metacrylate, 31 1/2 x 22 13/16 x 22 13/16" Manufactured and lent by Flos Available from the MoMA Design Store   In traditional hanging lamps, the glass or metal hemisphere that acts as a reflector and hides the bulb, and a layer of translucent material placed at the bottom to diffuse the light are all contained in one compact shape. In Frisbi, a small chromed dome reflects the cone of light onto a diffuser disc that looks suspended in mid-air, and beams it through the hole at its center.
