In bark rubbings I would like to think of the city as a forest of textures. A forest in nature can be seen an experience of living architecture. It is a medium that connects earth-human-sky. A walk through a forest has a texture of densities of vegetation, and within that varying densities of species, each with their own texture.
The city can be imagined in a similar way, certain areas are more or less dense with buildings and people. The buildings' canopy is higher or lower depending upon use or neighborhood. When you look to individual buildings, each facade has its own texture. The idea is that the visual textures and energies of the living and built structures project out into the spaces that surround them. By wearing the vest and walking through the spaces, one can experience them. The textures range from smooth rolling waves up and down the body, to stochastic full body bursts. Timing and intensity of the vibrations vary depending on the participants movement, much like how the sensation and impression changes when you vary the speed and pressure of charcoal while making a rubbing over a texture.
