In today’s Weekend section, we picked 10 amazing art objects, and we’re inviting you to choose your favorite. Possibilities range from a portrait of Kate Moss at the National Portrait Gallery to an all-orange room at the Arlington Arts Center. There’s even a 29-foot-wide print that’s made up of tens of thousands of tiny figures, each smaller than a dime. Check them out in our photo gallery, and then vote in our poll. And go see them — many are on exhibit for only a short time.
