Sunstroke was a solo show conceived as an installation at Galeria Cave in Fortaleza, Brazil. Drawing from the research project The Right to Shade, it brings together ecology, data science, architecture, cosmology, and digital technology. Curated by Lucas Dilacerda, the exhibition focuses on the high sunlight incidence in Céara, and was developed during the international residency “Mormaço: art, climate, and resilient ways of living in cities”.
“Through a poetics of data abstraction, Mari uses color and form to map a metaphysical cartography in which fluorescent yellow indicates sun exposure and gray signals brutalist concrete areas. The artist appropriates technologies originally developed for mass surveillance and control, subverting their function for poetic purposes and to generate critical reflections on the present.” (Lucas Dilacerda, curator)
February in Fortaleza, 2026. Acrylic and latex on canvas. 10 x 10 cm each. This series of twelve geometric paintings refers to the twelve hours of the clock, in which we perform a mathematical calculation of the intersection of solar incidence, building height, and shadow projection to determine equal areas of light and darkness at a specific hour of the day in Fortaleza.
Cityscape I, II and III, from the series Color Syntaxes, 2026. Cement, acrylic, and collage on paper. 20 x 28 cm each. These drawings with cement paste were like a diary of personal experiences in the city, where sunlight intersects with the city’s concrete surfaces.

Sunstroke, 2026. Looped video, no sound. The video that gives the exhibition its name uses the loading symbol to evoke the shape of the sun and, at the same time, machine thinking, which operates on a temporal scale distinct from human time. An essay to transform anxious machinic time into a meditative natural experience.
Exhibition views. “Mari produces an absolute synthesis of space through essential geometric forms. She draws on sacred geometry to approach a cosmology of heat, grounding her practice in the profanation of rational technologies to create intuitive, abstract, geometric, organic, and world-sensitive forms.” (Lucas Dilacerda)

Concrete, 2025. Cement paste and acrylic on canvas, 10 x 10 cm.
