Circle Explorer <http://www.squeakland.org/showcase/project.jsp?id=10212>-
Which lets kids play with inscribing and circumscribing a circle with
triangles to get a better understanding of Pi.

Polygon Maker <http://www.squeakland.org/showcase/project.jsp?id=10215> -
The "Hand me Polygon" button uses make a sibling instance, could have used
copy but I wanted the new Polygon handed to the user so they could place it
where they wanted.

M&M Artifact <http://www.squeakland.org/showcase/project.jsp?id=10524>s -
This has a bunch of different samples for kids to explore multiplication,
fractions and a number is all the ways you can name it.
