This volume of Incomplete Works is a compilation of twenty four items, each of which draws together: 1. an extract 2. a Cosmological Leap. The extracts are reflections on the nature of colour, they are selected from Doctor Watson Architects' library of texts about art, architecture, philosophy and science. The Cosmological Leaps are reproductions of digital image files, they were produced by Doctor Watson Architects as part of their on-going project that is generically known as Air Grid.
