E-book for children where the story depends on the outside weather

"Mousey Howsee and the Rescuers" is the first interactive e-book in the world where the story depends on the outside weather and the time of the day! Watch the trailer here: http://www.goodbuzz.org/!dcd1d240ad30 

Children are encouraged to read and observe the nature. If it's snowing outside, it's snowing in the story, if there is a good weather, the story goes another way. And you have to do nothing with it: just look through the window and run to watch what the Mousey Howsee is doing  

The e-book is created for iPhones and iPads.
