If you want to know the Maths behind the symmetrical designs, information is provided. If you just want to play and explore, it's set up and ready to go.
I made this design while watching my son play at the park.
And then by simply changing the symmetry, I got the variations seen below. Usually I would fiddle with the design and add more detail as I looked at the variations but I stuck to the original markings for the purposes of this post.
In the classroom this would be great for a symmetry lesson or an art lesson. I know that it has made me a lot more aware of the designs I see around me.
