Leston is a musician, artist, and developer based in São Paulo. His work investigates the relationships between sound, image, code, and permanence, exploring the sensitive interval that emerges between systems and perception and creating experiences where the living is not only what happens in real time, but what transforms before us. In his practice, programming ceases to be a mere tool and becomes a vocabulary, a way of building open structures and constantly transforming forms.At Leston's invitation, we developed the website conceived by Estúdio Cru, a digital space where the system that operates behind the scenes is brought together and placed in the foreground. Dwelling in the gap between error, the blue screen, and code, there is an explored interval.
