Cubes!

Sol LeWitt

From Wikipedia:

His prolific two and three-dimensional work ranges from wall drawings (over 1200 of which have been executed) to hundreds of works on paper extending to structures in the form of towers, pyramids, geometric forms, and progressions. These works range in size from gallery-sized installations to monumental outdoor pieces. Sol LeWitt’s frequent use of open, modular structures originates from the cube, a form that influenced the artist’s thinking from the time that he first became an artist.

Sol LeWitt: A Wall Drawing Retrospective, a landmark collaboration between the Yale University Art Gallery (YUAG), MASS MoCA (Masschusetts Museum of Contemporary Art), and the Williams College Museum of Art (WCMA) will open to the public on November 16, 2008, at MASS MoCA in North Adams, Massachusetts and be on view for 25 years.
