Mutations, Excerpted

From Caterina, via Sippey, comes this request:

  1. Grab the nearest book.
  2. Open the book to page 23.
  3. Find the fifth sentence.
  4. Post the text of the sentence in your journal along with these instructions.

Surprisingly, the book I have closest at hand also features Rem Koolhaas, mine being Mutations. The requested excerpt:

Once programmed, a synthetic city is made to proliferate and to interact with all the other cities, according to local conditions for the application of the model.
