The Swiss artist Andreas Luethi, born in 1961, lives and works in Uesslingen in the canton of Thurgau. He deals with philosophical questions on the subject of infinity. He is preoccupied with the aspects of space and time and how they can be represented pictorially. As an experimental project, he continues the number series of Roman Opalka (1931-2011). With no prospect of an end to this project, he strives to combine art and life.
