Social Buildings

Many buildings emit a cold exterior even though the people inside them are warm, and ironically, often feeling cut off from the rest of the world that feels cut off from them. It would be interesting trying to break down the building-wall by offering outsiders a feel for the insiders, without infringing on the insiders privacy.. and giving insiders a view of outsiders without being overly distracting.

Motion and/or infrared sensors could be used to detect movement both inside and outside and neon lights (or other lights/sounds/wind/etc??) could provide an abstract representation on the outside -- maybe with cartoonlike outlines or large pixelated reverberation. Similarly, pinwheels (credit to Hiroshi Ishii) or other ambient actuators could allow people on the inside to "feel" motion on the outside.
