The more generic term "ellipsograph" currently redirects to this article, and ellipsographs in general are described in a section near the end. In my opinion this article would be improved by re-organizing it to make the general topic of drawing ellipses be its root scope, with the elliptic trammel as a top-level section, as a sibling to other ...
