With her art, Regina showed how, in sculpture, mass can become dynamic projections of planes onto space, and how shapes can develop the lightness necessary to establish a new, multi-dimensional relationship with the environment and the context they exist in. One of the protagonists of Futurism, she investigated the aesthetic possibilities of different materials: tin, sandpaper, aluminium, iron wire, plastics. She went beyond the concept of statuary by continually experimenting to later arrive at MAC (Concrete Art Movement) with a lexicon of geometrical synthesis and lyrical abstraction.
