Some of my earlier projects are highlighted here. They include installations using mirrors and their reflection properties as well as experiments with cubes.

Solar Reflection of Oberriedner Star

The emblem of Oberrieden, where I lived, is a white, six-rayed star in a blue field (below left). In 2012 I was allowd to reflect that star from a mirror on the flat roof of an assembly room onto the North-Face of the church tower. In the morning on sunny days, while the sun moved from East to West, the reflected star moved from the right to the left. The challenge of the project was, to correct for the distortion, resulting from the placement of the mirror out of the way of the moving shadow of the tower (below right).

Solar clocks have existed for 3000 years, but this one is different. All existing solar clocks function using a shadow moving across an hourly scale. My idea was to cover hourly mirrors, leaving only the hourly numbers free. By placing these mirrors with the appropriate orientation in front of a wall , the projected numbers migrate from right to left, while the sun moves from East to West. In the middle of the wall a vertical line indicates the time. The left image below shows the situation at 3:05 p.m., when the projected number 3 has just past that line, number four is on right side of the wall, while number two is on the left, but was on the white line 55 minutes ago. The following time-lapse video illustrates this. Because the path of the sun changes through the seasons, the orientation of the mirrors needs to be adjusted every two weeks or so. This is made possible by turning the wood blocks and bending the aluminum sheets on which the mirrors are mounted.

The following time-lapse video illustrates the functioning through a summer day. 

Hovering cube becomes invasive

In 2017 I contructed an elegant cube that hovered between two trees at openArt in Roveredo. When that show was over, the cube was placed next to my house (first half of video below). In the spring of 2019 that cube multiplied and invaded the opposite side of my house, climbed up the balkony, the lanternpost and several trees in my backyard (second half of the video below).
