Horstman’s work can be seen across the United States. As an Artist-in-Residence, he created the “Rhythm Trail,” an environmental landscape sculpture for the Stone Quarry Hill Art Park in Cazenovia, New York. Other works include the “Golden Spiral Path,” an environmental sculpture using live plantings, earth, stone, wood, and other natural materials, now located in California’s Sierra Nevada Mountains; and the “Tree Hymn,” a sculpture of living trees, wood, and metal, created with high school students in Concord, Massachusetts.
This composition merges ancient concepts with innovative contemporary art designs and incorporates a common Chippewa motif. A diamond-shaped box made of steel marks the centerpiece of the sculpture. Nestled in a tree, Singing Tree, uses the wind (as well as viewer’s interaction) to release its simple, mournful chime.
