The work is composed of a wooden box with paint inside and PVC lamellas, the overlapping of these lamellar and photo-reflective structures in PVC creates a vibrating and moving effect that stimulates the visitor to observe the work from multiple points of view. The painting was exhibited at the 1st Biennial of the progressive museum of contemporary art in Livorno.
