Hamburg academy she continued to make cocoon-like things. She worked with padded body extensions and prosthetic bandages. In the late sixties she began creating performance art and continued to use bodily extensions. Body sculptures In 1968 Horn produced her first body sculptures, in which she attached objects and instruments to the human body, taking as her theme the contact between a person and his or her environment. Einhorn (Unicorn) is one of Horn's best known performance pieces: a long horn worn on her head, its title a pun on her name. She presented Einhorn at the 1972 Documenta. Its subject is a woman who is described by Horn as "very bourgeois", "21 years-old and ready to marry. She is spending her money on new bedroom furniture". She walks through a field and forest on a summer morning wearing only a white horn protruding directly from the front of the top of her head, held there by straps. These straps are almost identical to the ones in Frida Kahlo's painting Broken Column. The image, with wheat floating around the woman's hips, is simultaneously mythic and modern. Pencil Mask is another body extension piece, made up of six straps running horizontally and three straps running vertically. Where the straps intersect a pencil has been attached. When moving her face back and forth on a near a wall the pencil marks that are made correspond directly with her movements. Finger Gloves is a performance piece and the main prop of that performance piece and was done in 1972. They are worn like gloves, but the finger form extends with balsa wood and cloth. By being able to see what she was touching and the way in which she was touching it, it felt as if her fingers were extended and in her mind the illusion was created that she was actually touching what the extensions were touching. There is another piece that she did that is very similar to this one. It is part of her Berlin Exercises series done in 1974 called "Scratching Both Walls at Once". In this piece she made more finger extension gloves, but this time measured it so that they specifically fit the selected space. If the chosen participant stood in the middle of the room, they could exactly touch opposing walls simultaneously. Another piece that involves the illusion of feeling and one's hand is Feather Fingers. (1972).
