The cover photo contains the work 'Crucifera III ' (1964) by George Rickey. Born in 1907, Rickey dedicated his work to precisely-calibrated kinetic sculptures that he referred to as 'useless machines'. Crucifera III immediately caught my eye; its tree shape illustrating the landscape of our natural environment, embodied by the various independent yet interconnected elements which I depict as societal actors. Activated by the wind, the actors start moving, and in this interplay between the actors and the landscape, they affect not just each other, but also rebalance their landscape, making it fit perfectly with the content of this PhD thesis.Cover photo credits: Private collection.
