The “vesica piscis”, the “golden section”, circles, spheres – Hofstetter Kurt uses proportions and basic forms like these to develop synergies that lie between geometry and art. His “inductive rotation pictures” - asymmetric, aperiodic patterns and tilings created by geometric parallel shifts of cycles - remind of Arabic patterns and arabesques.  

The extreme shape of the sculpture “N.I.C. – nature is cool”, affected both by stability and instability, refers to biological structures found in the formation of leaves and inflorescences. The media art project Sunpendulum allows a parallel experience of day and night: Twelve video cameras – so-called “time-eyes” installed around the globe in all 12 time zones – broadcast pictures of the sky to twelve monitors which form a global sundial, to create a state of omnipresence of time, or rather to create an atemporal space.
