I don't know about American makers, but Panasonic has a huge, multi-story showroom in Tokyo with seemingly endless displays of household products. The pic is of an upper shelf system that electrically drops down from the cabinet instead of having regular doors. I can't see much use for this aside from households with someone in a wheelchair, however it's pretty cool and fun to watch. The showroom is part promotional but you can also order a whole kitchen there, including appliances and cabinets, and arrange for installation.
