The sculptor arranged colored tetrahedrons on the gallery floor to study light and shadow.

The artist constructed a delicate tetrahedron from thin brass wire and suspended it above the gallery floor.

The art installation consisted of dozens of brightly painted truncated tetrahedrons suspended from the ceiling.

The truncated tetrahedron, a convex polyhedron with four triangular and four hexagonal faces, is an Archimedean solid constructed by truncating a regular tetrahedron at each vertex by one-third of the length of each adjoining edge.
