The inexplicable, and the intentional exclusion of a possible interpretation of the abstract signs and their combinations, are the basis of my conceptual works. It is here important to me to remain close to interpretable signs and symbols, and to integrate this slightly baffling quality. This is only possible if the abstract signs have clearly delimited forms which have a conceivable meaning, and can be interpreted accordingly. .

My abstract signs are individual dissected elements reduced to simple forms, with a spontaneous design. I combine these individual signs into groups of 16, 9, 4, and 2. Or as clusters, mutations, overlaps, linkages, and entanglements. For example, a group of 16 can be combined in such a way that (without turning or mirroring individual signs) twenty trillion nine hundred twenty-two billion seven hundred eighty-nine million eight hundred eighty-eight thousand combinations are possible (combinatorics, permutation N = 16). 

The colors of my signs have no symbolic significance. The choice of color is spontaneously defined, always new from picture to picture or from group to group, and does not follow any concept. When, for example, a group of 16 pictures is monochrome and not colorful, the possibility of individual placement of the pictures allows for changes of the overall sign picture, and the color combinations can also be changed. In this way, I intentionally preclude my pictures from the question of the relationship between the psychological and the physical aspects of colors.
