I get such a kick out of creative calligraphers who try to "draw outside the lines" so-to-speak. Becoming good at that craft is all about rules and control, so it's fun to see them "let loose'
Would love to find more work (and English explanations) by Helga Ladurner. This image is from Here (German) where you'll find many more artists and examples of calligraphic creativity. Moving your mouse over the names shows the works.
