Alberto Biasi — Visione dinamica circolare (1964)

Executed in 1964, Visione dinamica circolare belongs to the most important historical period of Alberto Biasi's research and is one of the most significant examples of his early experiments with perceptual movement. In these years the artist developed an innovative language that overcame the traditional stillness of the artwork, turning it into a visual experience in continuous evolution and placing movement and perception at the centre of the work.

The composition is built through a precise torsion of thin PVC lamellae applied on panel. This system generates an optical effect that varies continuously with light and with the point of observation, creating the illusion of a circular form in constant movement. The dynamism does not derive from any mechanism: it arises exclusively from the interaction between the structure of the work and the gaze of the spectator, who completes the image by looking at it.

The choice of PVC, an innovative material at the time, testifies to Biasi's interest in technological experimentation and in industrial materials as expressive tools. The rigorous geometry of the composition is joined to a surprising perceptual fluidity, producing an equilibrium between precision of design and continuous transformation of the image. The work is an exemplary testimony of the pioneering season of Italian Arte Programmata, developed within the Gruppo N, and belongs to the period that collectors and institutions follow most closely in Biasi's production.
