On this and the next pages different options for structures are explained: more solid and self-sufficient, even without objects, next to more diversified and ephemeral. Various parts of the installations are designed for specific age-groups and present objects that are interesting for kids at particular stages of development. The structures are object-specific and their compositions are based on the proper understanding of weak and strong aspects of the existing collection. Some shelves remain empty awaiting for the next additions; and this is a promise that the WUNDERKAMMER will always be an ever-changing, exciting living organism.
