In sculptures made out of an array of discarded factory materials and old office furniture, Nuno Sousa Vieira explores opposites: consumption and usefulness versus refuse and obsolescence; the mass-produced versus the handmade; function over form versus form over function. Sousa Vieira renders utilitarian materials useless, while referencing their former functions and investing them with new life as elegant sculptural works. In Próspero (2006), for example, he transforms two wooden stepladders, perilous to climb, into gently torqued sculptures of artfully composed vertical and horizontal lines.
