The chapter title comes from the fusion of concepts “echo” and “equations.” “Ecoações” contains, from the traditions, the Algarve handmade textiles, the regional pottery, and the characteristic sounds of the customs associated with these activities; from the theater, scenography and costumes; from the fine arts, the sculpture (of the human figure) and the murals in low relief; from digital media art, soundscape, digital interaction, and video projection. In Ecoações, the scenic space invites spectators to immerse themselves in the theme and to visit another dimension of heritage traditions, presented here under a contemporary aesthetic. The installation as scenography space implies all the theatricality of the visual narrative, hearing and tactile, giving the public the opportunity to explore tradition through the various senses. This article discusses the characteristics of the installation “echoes” that bring it closer to post-digital aesthetics and heritage expression, and the challenges of combining the scenic space, the traditions, and the digital media art.
