Designers are very good at making things, but medium design is less like making a thing and more like having your hands on the faders and toggles of organization. It is the design of interdependencies, chemistries, chain reactions and ratchets. It benefits from an artistic curiosity about spatial wiring or reagents in spatial mixtures, a curiosity about designing not a single object but a platform for inflecting populations of objects or setting up relative potentials within them.
