like the logo approach....
is a simple way to approximate a circle
could also use scratch's trig functions to draw a circle, but i guess the first is more what the bodily syntonic thing is about,,,how does it feel to walk around a circle

Circle is one of the hardest in Scratch. Unless I am missing a command.
Make math your own, to make your own math.

Forty shapes to make in Scratch <http://scratch.mit.edu/> or some other version of logo, such as Turtle Art <http://wiki.sugarlabs.org/go/Activities/Turtle_Art> . It's hard to see the thumbnail but click on it for a larger view.
This is one of the best sheets ever for teaching maths (designed by Barry Newell):
* the logo turtle or scratch cat acts as a transitional object between the concrete maths shape and the abstraction of the script that makes the shape
* the sheet includes both simple and complex shapes, increasing in order of complexity, there is a challenge there for everyone
* many of the more complex shapes are made up of combinations of the simpler shapes
