Yet, as Dorothy discovered, there is no place like home. With "Sol LeWitt on the Roof: Splotches, Whirls and Twirls" currently on view in the roof garden of the Metropolitan Museum of Art, and a pair of sculptures -- Circle with Towers and Curved Wall with Towers -- installed in Madison Square Park by the Flatiron Building in Manhattan, it's a good time to review the fact that scattered across Manhattan are a dozen sites with wall drawings by this mild-mannered, thoughtful 77 year old. East Side, West Side, all around the town, there's probably a LeWitt on view in your neighborhood.

About his wall drawings, LeWitt once stated, "I wanted to do a work of art that was as two-dimensional as possible." And, in the same declarative sentences published in Arts Magazine in April 1970, he noted, "Different kinds of walls make for different kinds of drawings." That is part of the pleasure of visiting the "New York 12" in a short period of time. They're tall. They're wide. They meander. They're interrupted by doors, a coat check, elevators and air vents. They are geometric shapes, clusters of lines, a rainbow of colors. Your grade school art teacher probably would have found them too elemental; and your arithmetic teacher might have shrugged her shoulders.

Still, it is clear LeWitt has achieved what he sought almost 30 years ago when he wrote, "It is the desire of artists that their ideas be understood by as many people as possible." Today, these ideas convey joy and ebullience.
