Step Inside the Termesphere Gallery and Discover Whole New Worlds!
Tucked into the hills just outside Spearfish is something you won’t find anywhere else in the world: a geodesic dome filled with spinning, hand-painted spheres that hold entire worlds.
Each Termespheres captures everything you’d see if you stood inside the scene and looked in every direction. Some explore famous architectural spaces like the Pantheon or Hagia Sophia. Others twist into surreal dreamscapes, geometric puzzles, and thought-provoking symbolism.
They hang from the ceiling. They rotate. They change as you move.
It’s part art, part illusion, and totally unlike anything else.
