There is an interesting piece by Gastón Gordillo on ‘Passion for Terrain’ at his Space and Politics blog. It’s mainly about wingsuit flying, but indicates some of the arguments of his book in progress Opaque Planet: Outline of a Theory of Terrain.
Léopold Lambert picks up on some of these themes in ‘Spinozist Body/Terrain’ at The Funambulist.
Gastón and I are organising two sessions on ‘Terrain’ at the next AAG.
