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

I've taken on your challenge and it's not easy! :)
Posted a few of my half-brained attempts on Youtube.
Search recent Turtle Art posts on Youtube.
hi dennis,
Good luck with it.
It would be good if Sugar had a website like Scratch where work could be posted in one place on the web - and the software made that easy too.
I had a student last year who nearly completed all 40 challenges in Scratch and I asked her to tidy them up and post to the Scratch site. It didn't quite happen because we ran out of time but the concept was good.

I looked at http://www.youtube.com/watch?v=1PqN9HKbeeU
In the video you say its a pity you can't collapse named stacks, which is true, but you can scroll the canvas and shift stacks into a less viewed area of canvas.
