The organic forms totems are really neat:

Pinch pot forms (fusing two pinch pots together) are made and
textured. Holes are made in forms to mount on a rod. These would make
a neat garden installation.
This idea has been posted to the list before.... If any one does it
with students, send me a sample for Incredible Art Department. No
lesson plan is necessary.
I have added a link to this school from Secondary Art Departments page.
