An impressive iPad app from the Museum of Modern Art goes beyond simple exploration of the museum's collection to create a really interactive experience for kids, and maybe adults too. You can look at the creative processes of artists, but also do group drawings (you draw the head, I'll do the body) and get inspiration from the 'ideas section.' You can also create sound poems and collages. All work can be saved and shared via social networks. $4.99 in the app store.
