Ghost Scraper is a wireless device for sensing the urban landscape,
using tectile sensing for sonic activation of ghosts.
Ghost Scraper is sensing the invisble sonic layers in the materiality
of the city, such as concrete, aspalt and other construction materials in
the city, to sense the memory of ghosts, the spectral aspect of the city.
It is using embedded computing and real-time audio processing in Pure Data
for the sonic interface. Ghost Scraper is an auditory face to the city to
to explore the aspects that are not visible, to reveal the hidden.
