CADA is an art group that makes software for the public realm and exhibitions. Formed in Lisbon in 2007 by Sofia Oliveira and Jared Hawkey, its work is intentionally playful, designed to activate experiences that are both personal and question our relationship with technology in everyday life. It also organises events and workshops to extend participation in digital cultural practice. The group has exhibited across Europe and in Brazil.

CADA has received public funding from the Creative Europe Programme of the European Union, the Directorate-General for the Arts (DGArtes) of the Portuguese Ministry of Culture, the Portuguese Foundation for Science and Technology (FCT) and Lisbon City Council.

A MOEDA (The Coin) 2013 – ongoing
A MOEDA (The Coin) is a digital artefact that wants to travel around the world.
A semi-autonomous object passed between human hosts, on a journey defined by a desire to eventually return home.

TimeMachine 2009-14
TimeMachine is an Android application which aims to capture the elasticity of time experienced in everyday life, and translate it into a meaningful image.
TimeMachine is a CADA project developed in collaboration with CITI (Centro de Informática e Tecnologias de Informação) at the Nova University of Lisbon.

Emotional Object 2008-09
Collaboration with Adriana Sá and John Klima
Emotional Object is a multi-user game that invites participants to act upon a mechano-sculpture and a musical composition through a digital interface. The player proceeds while speculating about which emotion will result from a determined action, and about the effect of the individual over the collective.

Today 2007-08
TODAY is a mobile phone application that visualises personal communication.
It sits on the periphery of the machine, monitoring our connectivity through the number and type of calls we receive, subtly displaying them back to us, in the form of a generative graphic. What lies at TODAY’s core was the idea of using personal data as the basis for an aesthetic system, while providing individuals with a visual diary of their communication patterns., 2013 version
Android version with new visual system and features.
