The Apple store in Berlin has been designed with special window "walls" that look out onto the public passage. Projectors with images of dancers interact with people passing in front of the store.

The windows present a similar appearance to the well-known iPod advertisements; they allow everyone passing by to participate in Apple's branding scheme.
The windows provide an interactive opportunity for passersby; anything that makes people dance in the streets must be good.
John Shirley writes about something similar in Freezone, the 1985 cyberpunk classic; consider the reactive wall:
...It started out butch, its walls glassy black; during the concert it went in gaudy drag as the sound-sensitive walls reacted to the music with color streaking, wavelengthing in oscilloscope patterns, shades of blue-white for high end, red and purple for bass and percussion. Reacting vividly, hypnotically to each note.
