    She is quite wonderful. Vi now works for Kahn Accademy.
    I hope to meet her some day, but with my luck, she'll be
    wearing gloves and I won't recognize her

    Her rapid-fire speech reminds me of my ex-wife, except Vi doesn't speak in circles and actually has something interesting to say.

    I was introduced to hexaflexagons a half-century ago
    in Martin Gardner's first Scientific American book.

    I cut equilateral triangles from file-folder stock
    and used surgical tape for the hinges.
    I still have them and they work fine.

    If you can follow her rapid-fire instructions,
    give them a try. .They are fascinating!
