The starting point for this project is the often-uttered phrase “I want to make a difference”. It enabled people using a new building at the University of Plymouth to do so, by pressing a button mounted on a plaque in an atrium. Over two weeks, each time the button was pressed, the building was briefly full of the sound of voices declaring they wanted to make a difference. The more times it was pressed, the longer the duration of the audio piece and the more voices used. A website documented how often the button was pressed, shown against other key data such as the temperature in the building. On each button press, an email was sent to the Vice-Chancellor saying that someone wanted to make a difference.
