While working in Pilsen we asked residents of the city to draw maps on our hands that detailed the routes to various point of interest in the city. For example, one hand-drawn map depicted the route from a coffee house to the cathedral in the city center. Another illustrated the route from the technical university to a shopping mall. We then photographed and converted those informal and highly specific maps into folded paper maps that resembled a typical tourist map of the city. Finally, with new maps in hand, we returned to the city where we asked passers-by to help orient us.
