The public parts of my notebook.
Blow says that a designer can create a system that exhibits behaviours more complex than the rules that govern it. He says that, in all systems, there are places that reflect our corporeal universe. These places are truths in our real lives. He says that a designer can design by creating and exploring systems and then isolating and presenting the truths he finds.
A while ago, I saw another talk by Blow that is a development of these themes. It is also very good, but less focused and a less pure expression of the central idea.
