Curve-stitch Cover Art

Much to my delight, I received a large envelope from Australia yesterday. It contained copies of the latest issue of Vinculum a journal of the Mathematical Association of Victoria  aimed at mathematics teachers. The cover art is my curve-stitch isometric cube design. I had lost track of the publican date, so the arrival of the envelope came as a pleasant surprise.

Journal editor Roger Walter requested permission to use my design, as his “From the Editor” column in the current issue is largely about curve stitching.

I suspect that most readers have no idea what a vinculum is, by the way. I certainly didn’t when I received my first e-mail message from Roger. (Dictionary.com notes that “[f]ew English speakers likely know this word.”) A vinculum can be a bond or tie. In mathematical notation, it is a horizontal line used to group expressions in some way. The horizontal line in a fraction, for example, is a vinculum. (See Wikipedia for more details.)

You can learn about curve stitching and see more of my curve-stitch designs on my Web site here.
