Symmetry Artist

I was observing a geometry class today, and one of the lesson resources was Symmetry Artist from Mathisfun.com.  I was so excited by this resource that I could hardly focus on the lesson.  If you've never seen this resource before, it looks like the screenshot below:

 My five year old created the drawing above.  When she was finished I told her to pick a different number of "petals", and she chose 9 (shown below).  No I'm not trying to show off.  Either you see her art or mine.  The point is that this tool is both amazing and easy to use.

What a find!
