"The closing of a door can bring blessed privacy and comfort -- the opening, terror. Conversely, the closing of a door can be a sad and final thing -- the opening a wonderfully joyous moment."

-- Andy Rooney, American author and news commentator.

During the five years Yokohama-born artist Hiroharu Mori was living and working in the United States, he became interested in how the open social environment there contrasted with the atmosphere in Japan, where spontaneous interaction between strangers is rare. And so one day he took his studio door right off its hinges, mounted it on a dolly attached to a shoulder harness, and rolled it through the streets of Boston. He then invited anyone and everyone to drop in on his now doorless studio for a visit.
