Other interpretations of LeWitt's Wall Drawing #11 seek symmetry in patterns of grid-like repeated lines. This one instead embraces all four distinct combinations of "three of the four kinds of lines", and replaces the license to add repitition (which creates a unified pattern out of the four quandrants) with a license to add color (which distinguishes the four separate figures).
