Lygia Pape (7 April 1927 – 3 May 2004) was a Brazilian visual artist, sculptor, engraver, and filmmaker, who was a key figure in the Concrete movement and a later co-founder of the Neo-Concrete Movement in Brazil during the 1950s and 1960s. Along with Hélio Oiticica and Lygia Clark, she was an important artist in the expansion of contemporary art in Brazil and pushed geometric art to include aspects of interaction and to engage with ethical and political themes.
I saw below at the Art Institute in Chicago recently, part of an exhibition of her prints.
Claudia de la Torre: Palimpsest at Miriam embodies the true character of this form through an interactive, site-specific installation that invites visitors to collectively produce the work over time. The work utilizes basic materials and prompts for engagement as the foundation for a performed drawing, print, and ultimately a publication.
