Art in 3-d for elementary classes

Pageflakes is like a quilt of a page, and just as busy. My Pageflakes page includes several art museum feeds, and I heard back from one of them with suggestions for others. I tried to include a great drawing program my son developed for homework, but was unable to do that. I can see a Pageflakes page as a great early starter, early finisher for classes, even if only a couple of students explore or do assignments from it with it projected for others to see.
