This installation was created during the 1st Parametric Design Workshop at Universidade Católica de Pernambuco (UNICAP), Brazil, where 25 architecture students and young architects explored Grasshopper and Rhinoceros software. Led by professors Victor Sardenberg, Ana Luisa Rolim, and Robson Canuto da Silva, the workshop aimed to construct low-budget installations on UNICAP's campus. "Sonar" was one of these projects.

​

Unlike typical Brazilian campuses, UNICAP's campus integrates traditional urban blocks in downtown Recife. The "Leisure Street" serves as a bustling social hub, hosting various activities and conversations.

​

The concept behind "Sonar" was to capture the dynamic relationships of "Leisure Street" through its ambient noise. Fifteen-second recordings were taken at 15-meter intervals along the street, condensed into one. Using Processing software, these recordings were converted into 3D data resembling a cloud of points. This data was then transferred to Grasshopper.

​

In Grasshopper, the central portion of the cloud was selected for its complexity and converted into a NURBS surface, scaled to fit the campus corridor. To simplify construction, the surface was fragmented into linear segments to maintain the original sound's curvature.

​

Constructed over two days, "Sonar" utilized simple materials for cost and time efficiency. Yellow nylon cords were hung from metal tracks on the corridor ceiling and walls, forming the installation's shape. Hand-painted red tips emphasized the sound-inspired design. Located in a bustling corridor, "Sonar" transforms the space, inviting interaction and curiosity from students and faculty, offering a unique tactile experience amid mundane surroundings.
