In his book Paths and Passages Hans Dieter Schaal visualises what a journey can feel like. In his fine black and white drawings different spaces are imagined not as they exist but as they are experienced. Some pathways are more detailed than others. In one, a linear line splits into different islands of conscious awareness. In another, a forest track starts out plain white until it is populated with tree stumps and logs. Throughout, paths unroll and become motion.
