Aoy lamp, 1975 Translucent and opaline glass, 23 5/8 x 11 13/16 x 11 13/16" Manufactured and lent by Flos   To use up the light that ordinary floor lamps usually waste on their stem, Castiglioni designed a translucent support, a glass cylinder a foot wide with an opening at the bottom for a cat to curl up where it's warm, and to allow for cleaning of the floor inside. All parts are made of hand-blown glass and are made to match, without any metal connections.
