My friend's friend – The concrete sphere is 130 cm in diameter. It blocks the path. It looks heavy and it is heavy, but it can be moved. It is unlikely that one or even two people, pushing it with all their might, can make it budge. It takes the effort of three or better yet four people to make it start rolling and to shift the location of the essentially classic sculpture. The interplay between sphere and surroundings changes every time it is moved. The gravel leaves permanent traces on the mother-of-pearl coating.
