Their final joint work, fabricated in Turin, Italy and titled Tumbling Tacks (2009), was designed for the Kistefos Sculpture Park in the countryside north of Oslo.

In 1985 they collaborated on Il Corso del Coltello (“The Course of the Knife”), a performance piece in Venice, Italy, with the architect Frank Gehry, whom van Bruggen had met in 1982 when she was on the selection committee for documenta 7 in Kassel.

She contributed articles to Artforum magazine from 1983 to 1988, and served as senior critic in the sculpture department at Yale University School of Art in 1996–97.
