Our approach to technology has changed fundamentally. Hand movements serve not so much mechanical actions as an interactive exchange between man and machine. In architecture, one finds similar phenomena. The technical development from mechanics via electronics to a digital networking of decentralized units is based on a functional tradition that leads today to efficient concepts for moving constructional elements. Although buildings are generally static objects, controlled modifications have always taken place. These are based on the need for a continuous adaptation of the human environment to meet changing spatial requirements or in response to cyclical sequences in nature, like day and night, summer and winter. Long-term change is met by single, irreversible modifications to a building; short-term, recurring modifications can be achieved with mechanical solutions.
