Tim Poston is a roving British geometer now based in Singapore, fascinated by the four continents he has lived and worked in, and the doctors, geographers, physicists, archaeologists, ecologists and such he has worked and published with. He places mathematics among the visual arts, and has co-authored heavily illustrated texts on General Relativity and on Catastrophe Theory: the TiZero Gallery in Torino gave a show of his figures and sculptures. As a founder of Reachin Technologies (Stockholm) he works to lay hands on objects in the computer's mind, from simulated arteries to art and industrial design.

Words are another pathway to the mind's seeing.
