The work Cachoeira, in the valley of the Anhangabaú and in the viaduto do Chá, had the intention of rethinking the space and its history, symbolically recreating the memory of the stream of Souls that passed through the region. Described a rapid and shocking flow, which never stops, as the volume of information and people that circulates through the city and often transcends the physical environment, becoming metaphorical. The work could be perceived during the day, but it reached its maximum impact during the night, creating a spatial and virtual narrative.
