DIF is the widespread museum of Formello, and like the bee, this museum moves “from flower to flower”, bringing art into homes, schools, shops, streets, and wherever people are willing to welcome and share it. DIF is a device based on the values of gift and hospitality, proposes a new model for sharing public goods and taking collective responsibility for them. Artists works are donated to the Municipality of Formello, which gives them to citizens who want to take care of them.
