Landing sites are local deposits of subjectivity that acknowledge and then redirect attention, allowing the user to think the process of thinking through architectural encounters. They offer navigational cartographies from direct perception to imagine perception, to the composite structure of a spatial model of thought through environmental "thinking-feeling". Landing sites affirm all awareness as both sited and spatial, embodied in a context. They envision the structure of the organism as inseparable from the operation of perception producing the subject.
