"K12 Star Stack" was created as a part of my "Stars of the Mind's Sky" series. It is a digital photograph of laser-cut acrylic stars, stacked on each other. It features all possible 12-pointed stars, and from above, shows all possible edges between 12 points. This is also known as a K12 graph.
This is a second photo of the star stack, shot from the other side. Foreshortening makes the stack appear pointy, though it's actually fairly cylindrical.
