Some things I think about:
• spaces in which the moment before something happens, happens
• built environments that set up a social dynamic
• choreography of everyday interaction
• personal space
• physical humor
• ergonomics
• objects that facilitate an exchange
• lapses in the utility of objects
• obstacles
• showroom displays of: door handles, plastic koi ponds, towel racks, hot tubs, prefab windows, bathmats
• hand rails
• slippages between the visual and the haptic
• imprints of things: in plaster, in paper, on the retina, on film
• shadows
• projections
