ABSTRACT
The design sketchbook appears as an inherently fluid transient space, since it functions as an in-between liminal threshold, as a portal through which creative intentions can find their fix in the world. This chapter explores the latent potential for the designer's sketchbook to perform as a dynamic, interstitial phenomenon, through which it is possible to evidence Gilles Deleuze's notion of the virtual and the actual. The contemporary use of the word 'virtual' almost exclusively binds its meaning to the world of digital technologies, becoming solely allied with the digital realm. The chapter represents the sketchbook as an effective tool for formulating an alternate mode of a design-orientated process; a mode effecting a more instantaneous, vigorous, and intuitive engagement with the materialization of ideas, concepts, and new ways of thinking. The chapter elucidates the significance of the term 'virtual' as a central part of sketchbook-praxis, reasserting both the original meaning of the word and its theoretical importance to Deleuzian philosophy.
