Between the silence of concentration and the tension of the next move emerges Acta rationis—an exhibition by Jan Hladil and HRTL, presented at (A)VOID Gallery as part of the 13th edition of the Spectaculare festival. From March 18 to April 1, the gallery transforms into a field where rational structures of thought flow into objects, sound, and image—where a chess game ceases to be a game and becomes a sensory experience. Spatial works by Jan Hladil and musical compositions by HRTL enter into mutual resonance, forming a living archive of decisions, memory, and error—legible traces of human thought in motion.

Opening: March 17, 6:30 p.m.

Opening hours: Every day, 5 - 8 p.m.

Acta rationis is an exhibition project that translates the record of a chess match—a sequence of rational decisions, moves, and counter-moves—into physical, sonic, and visual form. Chess appears here not as entertainment, but as a structured language of reason: a system of rules, tensions, and memory from which objects, music, and projection emerge.

Jan Hladil develops the sculptural objects and visual layer by transforming specific recorded games into spatial forms. Each object becomes a material inscription of a thinking process—a trace of strategy, rhythm, and error. HRTL’s musical composition operates with the same data and principles: moves, repetition, escalation, and silence, creating a parallel acoustic structure that corresponds to the visual system.

Projection connects these two dimensions and extends them through time—object, sound, and image entering into a dynamic interplay of resonance. The exhibition thus becomes a symbiosis of reason and perception, an archive of mental processes and their living interpretation. Acta rationis—acts of reason—are not presented as an abstract ideal, but as concrete, recordable, and re-readable traces of human thought in motion.

The exhibition is presented in collaboration with the Spectaculare Festival, The Chemistry Gallery, and AVOID Gallery.
