Smart Board Symmetry

At our new school we have these fancy Smart Board screens and I think it would be awesome to set up a few of them to let students doodle with a symmetry simulator. Here are some that I've found while I'm at home that I want to test out in my classroom.

It talks about the type of symmetry. For this we could lower a board to the shortest it can go and let kids play around.

Weave Silk is a pretty one:

On this one you can choose between 0 and 6-fold rotational symmetry. You can also share your results via email. Perhaps there's a way to print designs?

Math Is Fun has one, except I wish it had a full screen option:

I love that you can choose the symmetry: x-axis, y-axis, x=y, x=-y, origin, and none.
