Caletroscópio: the story of an exhibition

The Caletroscópio is an interactive installation featuring a collection of video poems viewed via projection, with interaction driven by computer vision. Each video poem was created individually using p5.js and assembled into a TilBuci movie for the presentation.

The Caletroscópio was first presented to the public at the Faísca Festival (https://linktr.ee/faiscafestival), which took place between May 15th and 17th, 2026 at Mercado Novo, in Belo Horizonte (https://www.instagram.com/mercadonovobh/). The work Caletroscópio is the result of a collective effort. Get to know some of those involved.
