A pioneering example of Alberto Biasi's celebrated optical research, this work features carefully arranged ribbon strips layered over a painted wooden board, creating a dynamic interplay of light, shadow, and perceived movement. The composition exemplifies Biasi's mastery of kinetic and optical art, inviting the viewer's gaze to shift and animate the surface with every change in perspective. Housed in the artist's own aluminium frame, the work exists as a complete, unified object — a hallmark of Biasi's meticulous and cohesive artistic vision.
