Moondog

Moondog is a minimalist sculpture created by Tony Smith in 1964. 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. This is the third of an edition of three in the series.

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

It was installed at the Museum of Modern Art.
