Statement

I gained my experience in art as a trained stone mason, wood carver and academic sculptor. Through my self-taught research on a new quasiperiodic growth algorithm (Quasiperiodic Succession), which was published in the prestigious Philosophical Magazine in 2007, I gained deep insights into the Penrose tilings. My artistic interpretations of this topic from the gallery „Quasicrystalline Wickerwork“ can be seen in IMAGINARY exhibitions worldwide. For the Bridges Conference 2025, I outlined the basic principles of these images and summarized them in the paper “Reflected Motifs in Quasiperiodic Escher-Penrose Tilings” in collaboration with Amrita Acharyya. The “Quasiperiodic Ballet Dancers” are the youngest image on this topic.

The “Great Quasiperiodic Cartwheel Ballet” appears to be freely composed, but it has a very high degree of order. In our this year's Bridges paper “Reflected Motifs in Quasiperiodic Escher-Penrose Tilings“ (co-authored by Amrita Acharyya), only the inner 50 dancers are shown. There you can clearly see that the outline has a fivefold rotational symmetry despite the asymmetrical interior. In the great version here, consisting of 110 dancers, the 30 female dancers in the outer ring show what is meant by doing a cartwheel. The five deep gaps in the ring must be filled by male partners. The technical realization of the great version in an appropriate size would be possible with digitally printed adhesive films on a large and smooth wall.
