http://www.wiki-how.com/Main-Page excellent to learn and share how tos! I have just Googled How to create a stop motion animation after losing my paper notes for this and found a great wiki with loads of helpful how to articles. I am considering uploading all the How to... sheets I have made to support staff using various software programs and web 2.0 tools - Photostory, Kid Pix, Voisethread etc. And there is a wikiHow app for iPhones and iPod touches too.
Here is the link to the article I will be using to support my animation work with the Digikidz next week: http://www.wiki-how.com/Create-a-Stop-Motion-Animation .
