Should a rainy day require an indoor activity, there’s still a week left to run, walk, and bounce through Anthropodino, Brazilian artist Ernesto Neto’s fragrant installation at the Park Avenue Armory. The magnificent see-through fabric structure occupies most of the Armory’s main hall. Wear slip-on shoes so you can dive into the ball pit, sink into the giant purple beanbag, or take a nap on the padded floor of the “igloo,” scented with lavender and chamomile. Closes June 14 ($10 adults, free for kids; 643 Park Ave., at 66th St.).
