Pyramid Sculpture

Fran sent this photograph from one of her walks and says: The "Four-Sided Pyramid" sculpture in National Gallery sculpture garden.. Sunlight changes your view of the blocks on each side.

Wikipedia says: Four-Sided Pyramid is a conceptual modular sculpture, by Sol LeWitt, in the National Gallery of Art Sculpture Garden. The artist created a plan and Four-Sided Pyramid was constructed by others, in 1999
