Seemingly suspended in midair are a series of wire dominoes and circled dots, including one real vintage domino and a square of blue to highlight the lower left corner. Behind the hovering shapes are shadows cast against the white background, moving as light comes and goes. If you stand so that one wire domino is lined up perfectly, you’ll likely find that another is now entirely out of alignment. Can you think of other art that changes depending upon how you look at it?
