From the Mediabistro article:
There are a lot of video apps out there, but Disney Infinity Action! app is perfect for younger kids – the free download lets you play with a few Disney characters and make homemade videos using pre-animated characters (or Actions!). Characters like Mr.Incredible, Jack Sparrow, and Sulley can all play with each other or with props from movies such as Tron or Toy Story. Once you’re done with your video, you can save it as an .MOV file or you can share the videos on Facebook and Twitter to get points, redeemable for more Actions, characters, or props. You can also buy them outright.
