I don't know if you ever noticed the very close relationships between the way William Gibson designed/imagined virtual space and gestalts forms !, for instance this kind of forms or relations :

He saw cyperspace has "A graphical representation of data abstracted from the banks of every computer in the human system. Unthinkable complexity. Lines of light ranged in the non-space of the mind, clusters and constellations of data." like he proposes in Neuromancer, 1984. Even though he did not give any graphical representations, readers were left by his very nice description. In my vision, the way he depicts virtual space (namely cyberspace) rely on Gestalt.

That is why the author talks about "the media gestalt" : "jacked into the media gestalt". Indeed, Gestalt theorists were intrigued by the way our mind perceives wholes out of incomplete elements. To the Gestaltists, things are affected by where they are and by what surrounds them...so that things are better described as "more than the sum of their parts". Gestaltists believed that context was very important in perception.
