We Make Stories (http://wemakestories.com)

All the tools are easy enough for six-year-olds to use, but there’s enough to keep tweens entertained, too. For instance, the audio book, which consists simply of dragging and dropping sound effects onto various objects such as cymbals, will delight youngsters just learning to read. Older kids will like Pop!, a tool for writing storybooks with fancy pop-up centers, and Comic Genius, for creating comic strips complete with talk bubbles and South Parklike characters. The graphics are gorgeous, the sound effects rich, and the writing clever. There’s even a tips section for kids on what makes a good story.
