Ceiling Painting, Yes Painting 1966
The interactive object known as Ceiling Painting was an important work shown at Ono’s 1966 Indica Gallery show in London. The viewer is invited in his or her mind to climb to the top of a white ladder, where a magnifying glass, attached by a chain, hangs from a frame on the ceiling. The viewer uses the reading glass to discover a block letter “instruction” beneath the framed sheet of glass: it says “YES”.
