This web site and related links consist of a collection of activities and ideas in which I have an ongoing interest. They are not my only interests, just ones that happen to be noted here in one group. Some topics are seriously off topic, but consistency is a well known hobgoblin, and does not always improve everything it governs.
Origami and geometry and algebra are intimately connected, and are topics about which I continue to learn new aspects of their relationships. I make a variety of origami pieces (mostly from paper), from geometric shapes and boxes and dishes, to animal pieces. See the origami link for examples, which can be purchased by individual arrangement. Private instruction is available, for beginner and moderately advanced folding, as well as in geometry and algebra. I'm also available for talks as short as one class or as long as ten sessions.
