Another interesting example of subjective mapping, in this case of different hutongs in Beijing:

URBAN CARPETS
Series of 8 carpets representing different maps of Hutong areas with a size of approximately one square kilometre and a population of 30000. Each of them has been isolated and presented as autonomous town within the big city. They are embroidered by hand with the same technique of the propaganda slogans on large fabrics used by the communist party during the seventies. The carpets have been filled with white wire wool insertions.  All along year 2009 the urban carpets will be shown to the Hutong dwellers inside the courtyards and on the public lanes in order to share the project with people and bring it back to the city districts it was inspired from.
Look at the different carpets here: red, cyan, brown, green, orange

IDENTITY
1500 red stamps on 1500 grey clay beijing bricks

Stamps have a central role in Chinese people’s life: they use them to confirm agreements and validate their actions. In a certain way loosing your stamp is like loosing your own identity. Each stamp is not carrying a name but it has been carved with a fragment of Hutong district map, a group of houses, a piece of city, to mark the relationship and identification between people and their living space. The installation is part of the Instant Hutong art project.
