South African sculptor Roelof Louw's Soul City (Pyramid of Oranges) (1967), comprises 6,000 oranges arranged in the shape of a pyramid that depletes as visitors help themselves to the fruit. This interactive element runs through Louw's oeuvre, with many of his sculptural works from the 1960s and 1970s being site-specific as well as audience-specific.
Louw studied and later taught at Central St Martin's School of Art, London. His work is directed toward developing a new understanding and definition of sculpture and has been featured in seminal exhibitions such as When Attitudes Become Form (1969) and Between Man and Matter (1970).
His work provokes debate and dialogue, whether by incorporating the Stars and Stripes, animal bones, or fluorescent tubes to make political and social commentaries, and is included in many notable collections including the Tate.
