Exploration, from 20 years ago, of the concept of the virtual in Deleuze, De Landa, Massumi, Grosz, Bergson, Zizek and others. This is the main concern though it is tie into VR and related technologies (as things were around 2004). I wrote this a very long time ago and never quite published it (I don't think I tried). So it's very much a draft. It's what I thought others were saying about the virtual then and how this might change thinking about working with VR technologies. If it's useful I'm glad. It may become a chapter in a book in a while.
