The Passiflora lighting fixture comes from a painted cardboard prototype made for the exhibition “Superarchitettura” (December 1968), a manifesto of Radical Design. The cardboard was replaced by a material transparent to light, transforming Passiflora into a truncated luminous column: a column whose deformed profile wavers between natural and artificial, in a game of allusions and ambiguities, corresponding to the statement of intent of Superstudio, summed up in the text Invention Design and Evasion Design.
