[8] Her time in Paris also inspired her to create "livable sculptures," notably La Destrucción, in which she assembled mattresses along the Impasse Roussin, only to invite other avant-garde artists in her entourage, including Christo and Paul-Armand Gette, to destroy the display.

[9] She earned a National Award in 1964 at Buenos Aires' Torcuato di Tella Institute, where she prepared two happenings: Eróticos en technicolor and the interactive Revuélquese y viva (Roll Around in Bed and Live).

These displays took her to nearby Montevideo, where she organized Sucesos (Events) at the Uruguayan capital's Tróccoli Stadium with 500 chickens, artists of contrasting physical shape, motorcycles, and other elements.

[7] She joined Rubén Santantonín at the di Tella Institute in 1965 to create La Menesunda (Mayhem), where participants were asked to go through sixteen chambers, each separated by a human-shaped entry.

Led by neon lights, groups of eight visitors would encounter rooms with television sets at full blast, couples making love in bed, a cosmetics counter (complete with an attendant), a dental office from which dialing an oversized rotary phone was required to leave, a walk-in freezer with dangling fabrics (suggesting sides of beef), and a mirrored room with black lighting, falling confetti, and the scent of frying food.

The coup d'état by General Juan Carlos Onganía in June of that year made her fellowship all the more fortuitous, as the new regime would frequently censor and ban irreverent displays such as hers.

Minujín delved into psychedelic art in New York, of which among her best-known creations was that of the "Minuphone," where patrons could enter a telephone booth, dial a number, and be surprised by colors projecting from the glass panels, sounds, and seeing themselves on a television screen in the floor.

[10] The Minuphone was designed and constructed, in collaboration with her, by engineer Per Biorn, who was employed at Bell Telephone Laboratories, and the work was shown at the Howard Wise Gallery in New York City.
