In my free time I create and sew unique mathematical geometrical toys for children 5 years old and older. Together with the mathematical institute of the University in Göttingen, I developed the "Kindergarten Koffer" - a suitcase with different puzzles: 8 mathemagic cubes, 1 Pentomino, 1 Sudoku, the magnetic dodecagon and the Maths Pie. I made many spheres with different tilings on the surface, and edge models from polyhedra. My hobby is sewing stellated polyhedra, quilts and other robust, elastic, haptic and soft toys/puzzles! My circular quilt: "Da staunst Du - 29 Bauklötze!" was shown in Germany during the year of math in 2008. I have enjoyed the bridges conference in Jyväskylä, Waterloo, Stockholm and Linz.
My puzzle shows a photo of 101 marble stones. Inspired in the pandemic to visualize a virus mutating to produce many variants, I designed odd little owls. Each painted owl is represented by a genetic code that specifies its appearance. The belly color corresponds to the ones digit, the back color to the tens digit. For example, yellow represents the number 0 and light green the number 9. If the owl has a yellow back and green belly, it's the number 09. If the owl has a green back and yellow belly, it's the number 90. In the bottom right corner there is a completely green owl: the number 99. I replaced the Arabic numerals with Greek letters to create names for 101 Steinkauz mutations. Missing puzzle pieces result in gaps in the owl family.
