Tatem is an interactive treasure hunt that leads users through the green spaces of their city. The focus is on experiencing the variety of treasures which offers us our environment. An app guides users through long forgotten shrubs, fruit- and other useful trees. They must master different tasks and puzzles that require a sensuous engagement with nature. The aim of this study is to provide a new real relationship with our immediate environment and thus offer an alternative in daily food consumption. Experience, enjoyment and fun serve in this case as a key to the discovery of our own regional treasures.
