My free November project for the Math Forum is up. It involves using a photo of a leaf, tracing around half of it, and investigating the overall symmetry of the leaf. By combining the leaf models you get from a few different photos, you can create a nice collage of colorful leaves.
You can also use rotational symmetry to create a nice wreath.
This is a nice project for math students, but it also can be used in art and science classes. Enjoy!
