It was quite fun for me, for the first time reading my writings in an American journal. I have written about the bird tetrahedron in Norwegian in Tangenten (2005) and I recently elaborated on this topic and expanded the original article into a new one for MT. You can read the English version on jstor or the august issue of Mathematics Teacher from NCTM. I loved the way they made those nice graphics and photos for the front and illustrations! There are also some templates you download in PDF from the Mathematics Teacher website.
