Hans Thierstein
As a former professional scientist I spent my life working at the limits of available knowledge and trying to transgress it. An involvement in such activities tends to leave its traces.
For the past ten years I have applied my creativity in various art projects. I focus on innovation in technique, aspects of surprise and on attractive form. I started out with installations, such as partially covered mirrors reflecting wandering symbols or words onto a wall or onto a church steeple. Using this principle I developed a new type of solar clock: I covered mirrors, leaving out hourly numbers. These mirrors were placed in a half circle in such a way that the numbers were reflected onto a wall, on which they moved slowly from right to left, while the sun moved from east to west. Each hourly number crossed a central vertical time-line at the actual full hour. The next project was a delicate a cube hovering in the air. An additional project was the invention of the quatroscope, which is a square tunnel of elongated mirrors that are joined at their long sides, similar to a kaleidoscope, but with four rather than three mirrors inside. The effect is, that an object placed at one end of the tunnel, when observed from the other end, is reflected repeatedly in four directions. Reproducing this feature digitally on a computer, leads to the emergence of totally unexpected and beautiful patterns. With these digital graphs (quatroscopies) I have made the transition from three- (my previous installations) to two-dimensional art (my quatroscopies).These activities are documented on my website www.hansthierstein.ch (in German).
Most recently my quatroscopies have become mobile to the tune of well-known pieces of classical music. A continuously growing number of such AUDIOQUATROSCOPIES can be enjoyed on my YouTube platform. www.youtube.com/@audioquatroscopy
