“ The Apple and The Sock, like most of Gert's works, is very simple in concept. The figure is modeled with total fluency in the interaction between two artifacts that articulate interchanging meanings. It is interesting to see this fragile crossover between sculpture and installation in different works, in a language where the object is a performer who improvises his place in the scene. “
