Let's Play House
You may not be living in the midcentury ranch house of your dreams, but your kid's dolls can. This genius portable dollhouse from the Museum of Modern Art is composed of six nesting boxes that become walls, and includes flooring, punch-out furniture, and vinyl clings of accessories like plants and lighting. The equally cool family of punch-out dolls is sold separately. See ya, Polly Pocket.
