1. A viewer configured to rest upon a surface that bears coded data, the viewer including:

  • memory configured to store display information;

    sensing means configured to sense at least some of the coded data when the viewer is resting upon the surface;

    processing means for decoding at least some of the sensed coded data; and

    a display configured to output display data to a user;

    wherein the processing means is configured to;

    determine at least some of the display information based at least partially on the sensed coded data;

    generate the display data and supply it to the display, wherein generating the display data includes manipulating a position of the display information based at least partially on the sensed coded data to at least partially take into account the position of the viewer relative to the surface, the position of the viewer being determined at a higher resolution than is encoded directly in the coded data by determining a location from at least some of the decoded data.
