350 W. Broadway between Grand and Broome Sts. P.S. 3 hosts this interactive installation as a fundraiser for the school. Little ones can climb a graffiti wall, throw a ball up at a "sound mobile" and frolic among the artist-created playspace. On the ArtPark's final day, kids can take part in the Arts Festival (March 30, 12–6pm), where they'll construct puppets, build fairy homes, create comic books and learn a flash mob routines. Workshops are $10 each and online registration is required. Ages
