One of the works hung on the rectorial building depicted Bulu's shadow as a clown, as the official is seen mostly as a mouthpiece for the government.
Meanwhile, academics have been continuing their peaceful protest in front of the rectorial building despite bad weather conditions, standing with their backs to Bulu's office with umbrellas in the rain.
Boğaziçi members are calling for democratic elections to be held to elect a rector, as the appointment of Bulu via presidential decree is considered a massive blow to academic freedom.
Although police crackdown on protesters and students has eased over the weeks, officers remain in barricade at the school's gate.
