Apartments in a high-rise building are a little repeat-repeat-repeat module that create exactly the form that Andy Warhol called mini-art. When you repeat the apartment form hundreds and hundreds of times in a small space, such as these high rises, you really switch into tribal or cave world. And these people, therefore – I hadn’t realised it really until we sat here a few minutes ago – these people in these new types of cave dwellings really depend upon electric information for their existence.
