[math-fun] Outside In written accompaniement

I was recommending the video Outside In, about turning the sphere inside out to a friend. The VCR tape of it I have would be of limited usefulness even if I could find it, but it was pretty easy to find on youTube at https://www.youtube.com/watch?v=wO61D9x6lNY But the VCR tape was accompanied by a wonderful written guide, which had marked sections so that it could be read at 3 or 4 different levels of mathematical sophistication, and I can't find my copy. Does anyone know if this is available somewhere, online or otherwise? -- Andy.Latto@pobox.com
