Nulltidão is an artistic installation that reflects about the notion of group identity vs personal identity. In most cases, when the group prevails, individual identities are dimmed in favor of a group consciousness.

The installation was comprised of a video hall located in the cafeteria of the School of Arts (UCP) displaying a live image captured by a video camera, showing the tables and users of the cafeteria. This image would gradually fade to an image of an empty cafeteria depending on the number of users present in each moment. A rough approximation of the number of users in the cafeteria was given by counting the mobile devices using Bluetooth.

The project was programed in Processing and used DiABlu System.
