Just found (thanks Kurt) a cute little stick-figure animation program called Pivot.
It allows you to create simple animations and play them back. It is comparable to Paint in ease of use and would be particularly good for younger kids - although Kurt, who is 13 is having fun with it too.
I wasn't able to work out how to load an example to my blog so if anyone else can please enlighten me!
Here is a youtube clip I found apparently by the creator of Pivot.


Blog soon, Phil
