Gestalt conveys information qualitatively, and data sent or received about anything arrives all at once for interpretation by the mind of the Citizen in all its aspects simultaneously, resulting in an experience of immediacy. A citizen need not consciously consider the information sent (as in Linear): Gestalt operates rather entirely or almost entirely subconsciously. Citizens use Gestalt to create "icons" for themselves — "visual" representations within Scapes (Gestalt "areas" or "spaces"). Citizens also use Gestalt to convey "Tags": packages of information described as like an odour or essence, which any other Citizens within a range of several delta (or who happen to "read" for specific Tags) can gather. Each Citizen has a unique Tag which identifies them as a particular person, regardless of their other appearances, and citizens may emit Tags for other purposes as well, as when Citizens need to convey and understand arbitrary information instantly. Early in the novel, for instance, Yatima learns about an asteroid in the real world by reading its tags subconsciously, which precisely inform ver about its properties such as mass, velocity, rotation, composition, emission spectra, and other such data discernible to the Coalition's satellite network. Later on Earth, however, when ve and Inoshiro inhabit derelict Gleisner bodies, Yatima must remind verself that Fleshers are real people, even though they lack tags identifying themselves as such.
