Dialogo is an abstract 1971 sculpture by Virginio Ferrari, installed in front of Pick Hall at 5828 South University Avenue on the University of Chicago campus, Illinois, United States. The work is famous because of the shadow it casts that resembles a hammer and sickle.
Each year, a crowd of several dozen curious bystanders gathers to observe the formation of the shadow around noon. Ferrari himself has denied that he intended his sculpture to cast such a shadow.
