I would like to talk about the mechanisms I created for an artist residency I had at ESA's technical facility this summer. The appendages I produced are caricatures of the scientific instruments used in space exploration. Rather than the pursuit of collecting data, their functions are inspired by the human need to be personally expressive. I will explain how I made them, also why I believe its important to create "serious nonsense", in a world where there is pressure to produce practical tools.
