In his later years, Copello remained prolific, participating in various exhibitions and producing primarily graphic and digital works. Prominent among these was his 2004 revival of "Piece for the Insane", his collective performance thwarted in 1973 by the coup d’état. For this revival, he collaborated with theater students from the Arcis University, featuring Vicky Larraín, an original member of the actors’ collective in 1973.
