The theme is observation and analysis with the help of classic methods of visual art (visual perception). The medium should be self-explanatory, even if the language and the other senses have a deep meaning. In this context we ask ourselves if shit actually stinks or not. Does it stink because society taught us that it does? Does it actually stink? How can smell, taste, sound or tangible experiences be portrayed in artistically?

The following works covered the theme of a picture's real volume in relation to the volume that is aimed at. I deal with the problem or fact that no real two-dimensionality exists in pictures. Two-dimensionality only exists in our imagination. The picture with its space, volume, frame and restriction was the main theme of my work during the last years of my studies and continued to be an important theme for a very long time. Objects were created that used the wall as background and grounding at the same time. In contrast to painting and drawing on paper, the boundaries and restrictions dissolved here. However, I came to realize that the shape of the wall and the exhibition space are such boundaries and restrictions as well.

Just like space is related to the objects, so the observer is, too. Each object has its unique colour and three-dimensional shape. The theme of the works was the perception of the object and its shape, the position of the observer in relation to the object as well as the observer's movement in space. Space itself, however, surrounding both object and observer, was not part of the works.

These works cover the same topic as the previous work. And another thought adds to this. The canvas is made of woven threads. Which means that in painting one colours threads.
After that one perceives the colour plane. But I have used a reverse process. Coloured threads were pasted on a white canvas with a 1 mm distance between the threads. Is this therefore painting?
1. Background (white canvas) and foreground (black threads) lose their classical relation to each other.
In this work the background becomes foreground and the foreground becomes background.
2. One sees different shades of grey to black from every viewing point. Which led me to the question „Why do I have to look at pictures from the front?” and „Does one have to paint by hand to create a painting?”

The investigation of the relation between colour, surface, space and perception was the subject of my postgraduate studies. The works were painted colour planes of identical colour and size but with different surface qualities (matt or glossy) and different distances to the wall. This work was an attempt at investigating a plane's depth. How does the viewer perceive painted surfaces that are on one level but have different surface qualities?

Painting is not necessarily two-dimensional, even if it is so in my head. I visualize myself painting, incorporating all possibilities of composition. I envisage my paintings, the thickness of the paint, how and why I make use of what technique, how I apply the paint, which carrier I use, etc. This means that I use my sense of touch in its everyday meaning as well as the sense of touch of the eyes, not only thinking in colours but also "seeing" weight, temperature, etc.

Colour in painting is strongly influenced by the background (the colour of the wall, the frame) and also by the light surrounding it (darkness or brightness, for example). My thoughts on colour do not only relate to the surface of the canvas.

Before thinking about painting (what is on the canvas), I wanted to find out if there is any need for colour and, if so, why colour is needed. Light contains a multitude of colour nuances. Does this not suffice for painting? As Frank Stella said: "what you see is what you see". There is the portrait, still life, abstract, landscape, etc. - different categories. But actually we only look at the colour, its composition and materiality. So this categorization is only imaginary.

"Überlegungen zum Mechanismus der Erinnerung"

A memory is composed of many different parts. It can be conscious and subconscious and has an individual meaning for each person, even when the memories come from the same experience. The weight of the memory is different every time, depending on the person, the moment, the situation, etc. Intentional and unintentional pictures were taken on 8 films in Bedburg-Hau, on the site of the "Rheinsche Landesklinik" (Clinic for Psychiatry and Neurology). The resulting approximately 290 (5x7 inch each) pictures were printed.

Each print carries the number of the corresponding film and picture. Some prints are cut to 1/3 inch by 1/3 inch, others are left uncut. The pieces of each cut picture are kept together in a filmcase (numbered corresponding to film and picture), to be collated/pasted on the panel later. Some pieces left in the filmcase are not collated/pasted. Each finished work consists of the pieces of only one print.

"sur la structure de l'image / de la perception"

I cut prints of my own photos, taken since 1989, into pieces of 1 x 1 cm by hand. This action is part of the work "ZWISCHEN ERINNERN UND VERGESSEN" (Between remembering and forgetting) - see also performance. For "sur la structure de l'image / de la perception" a section of these photo pieces is pasted on 12 multiplex panels of 120 x 180 cm each in random order. The 12 panels correspond to a 135 mm film with 12 pictures on a scale of 50 : 1. The distance between the panels is in approximate accordance with the distance between the pictures on a 135 mm film (50 : 1). The wall for presenting the panels should therefore be 25 m long. Alternatively a presentation in two groups (of 6 panels each) or three groups (of 4 panels each) is possible. This would correspond to the standard size of developed negative strips in Germany, France and Japan. All 12 panels should be exposed together.

For Japanese tourists Lucerne is the epitome, the symbol of a Swiss town and a popular holiday destination. The "Lion Monument” is an integral part of every city tour of Lucerne, just like the group photo in front of the lion.

"kult.our” was a city tour by Lucerne’s free theatre scene, for the people of the city, with stations in public space and the town’s free theatres. In front of the „Lion Monument” I told the „kult.our” group, in Japanese, the story of the "Lion of Lucerne” which was erected as a reminder of the courage and loyality of the Swiss Guard, devastatingly beaten defending King Louis the 16th of France. Most of the „kult.our” participants were from Lucerne and heard my tour about „their” lion monument in Japanese... Eventually, there was the obligatory group photo.

Tourists were observed as tourists, and because of the tourists locals became touristic objects.
In exactly the same way theatre group and audience became observed objects too.
