Among the people I know from the National Film and Television School is Helen Piercy - with whom I have previously worked on an animated sonnet by Shakespeare voiced by Alan Rickman, and various school projects.
Helen is currently doing a lot of work with children and young adults in the form of animation workshops across the UK, and as a result was approached last year to write a book/ kit to help children make their own animations.
This book has now been released, and it's fantastic. I have a copy in my edit suite, and it's a big hit with the animators (and others) at the studio. The age guide is ages 8+, but there have already been reviews from much younger children starting to make their own films using the book and kit as a guide.
The kit includes several sets, characters, and props - plus a "director's handbook" which gives an introduction to animation and different styles, as well as hints and tips on making your own films. Find out more at the webpage on Helen's site, or by watching the trailer below:
