Work composed by a set of interactive urban furniture that seeks to break the boundaries between design, architecture and urbanism through digital technologies. The project was born from a simple invitation to passers-by to share a secret of their intimacy. The depositions, recorded anonymously, were successively stored and made available in the Collecting Chamber of Secrets, the centerpiece of the entire work. The project was completed by an activation of the rest of the furniture, through an interactive game of light and sound. All the furniture was painted with the colors of the flags of the countries of the main groups of immigrants that populated the district of Bom Retiro.
