Momento Monumento is a light and sound site-specific installation designed for an abandoned 20-floor tower in Sao Paulo. Each floor represents the key of a giant vertical piano: when the note is played, a strobe light illuminates the corresponding floor. Initially planned for 2009, "the year of France in Brazil", Momento Monumento was to be presented at the opening of Virada Cultural, but the event never took place. A prototype of the installation was exhibited at 104 in Paris in April 2009.
