Lego Art

These are all ways of beginning to define a work of art, to narrow it down. "Imagine you are an art critic whose mission is to compare the meanings you find in a wide range of individual artworks. How would you proceed with your task? One way to begin is to examine the materials each artist selected in making an object, image video, or event. The decision to cast a sculpture in bronze, for instance, inevitably effects its meaning; the work becomes something different from how it might be if it had been cast in gold or plastic or chocolate, even if everything else about the artwork remains the same. Next, you might examine how the materials in each artwork have become an arrangement of shapes, colors, textures, and lines. These, in turn, are organized into various patterns and compositional structures. In your interpretation, you would comment on how salient features of the form contribute to the overall meaning of the finished artwork. But in the end the meaning of most artworks... is not exhausted by a discussion of materials, techniques, and form. Most interpretations also include a discussion of the ideas and feelings the artwork engenders."
