Moondog is a minimalist sculpture created by Tony Smith in 1964.

[1] The piece is composed of 15 octahedra and 10 tetrahedra, and while perfectly ordered and symmetrical when seen from certain angles, it carries a strong tilt forward when seen from other angles.

The title refers to Joan Miró's painting Dog Barking at the Moon and a blind poet and composer named Moondog.

[3] In 1997, it showed at Paula Cooper Gallery.

[2] The work currently resides in the National Gallery of Art Sculpture Garden.
