Caroline, Here is a Etoys Minute <http://www.youtube.com/watch?v=xMDYf3_uovk> video showing how to animate a mouth. FYI, I created the mouth images with the polygon tool (if you shift click on a polygon, you can see its "handles") the circles in the handle let you move vertices and if you click on a green triangle you can add a vertice. From the menu in the polygon's Halo you can set the lines to curved.
The project "The Walkers<http://squeakland.org/showcase/project.jsp?id=7698>" by P. A. Dreyfuss shows a great example of what you can do animating polygons. Note: this project uses some extra code in the polygon object, but it can be done in Etoys by simply placing each "frame" in a holder and animating that way. The advantage of using holders IMO is that the kids can see what's happening more easily. Also you may want to check "Morphing<http://www.squeakland.org/showcase/project.jsp?id=7112>" by Kazuhiro Abe. I think kids will like this and at the appropriate time, with the appropriate guidance they could even write the morphing script themselves. But for now, they could simply re-use the script to create cool effects.
