The venerable carton to the right is the standard oyster pail , probably made by Fold-Pak of Norcross, Georgia. Nothing wrong with that design: it’s been around for decades and is cheap, functional and not so hideous in appearance as to put you off your lunch. The box to left is a different approach to the same purpose. It is cylindrical in form, has the same volume as the traditional box — one U.S. pint — and derives its strength from its curves and internal friction. It closes with a clever double-lock, obviating the need for wire or glue closures. Because the box is round and touches the table at only three points, the heat of the food is better conserved. Plus, the meal can be eaten directly, with the opened box serving as a plate. The name? Well, I am partial to Filipino adobo and it isn’t easy to find around here. In fact, if I don’t make it myself, it simply doesn’t obtain. I am releasing the design to the wide world with the hopes that some hipster entrepreneur will fill it with adobong manok and bring it to me. One can dream, eh? The design can, of course, be licensed by anyone anywhere for the usual filthy lucre, the coin of the realm. But for a limited time, the design will be available for licensing in the Philippines (including the Spratly Islands) for the fee of one box of adobo per week for life, assignable. In the spirit of good faith, here is a PDF of the template. Commerce passes everywhere, but the box also has uses for the casual home folder. For instance, it could be filled with pralines, pizzelle, poppadom et cetera and then suspended from the festive tree with a loop of knotted ribbon.

It is with some reluctance that I point at this video — not because I imagine it is sinful to do so, but because I have seen this film surface on the Internet before and the act of looking at it somehow makes it disappear. You tell your friends, “Hey, look at this!” And by the time they look, it has vanished. I took the precaution of downloading it, this time.

The proportions are pleasing and it reminds me of Philip Shen, the way it suddenly locks together at the end. I would call it simple , but it is manifestly not. The lines are simple. The pre-folding is persnickety — fussy, if you will — and pulling the legs down one at a time deforms the model in a distracting way. For all of that, I like this model. Maybe you will, too. Here are some diagrams . It’s called Brazier after a similar traditional model — the Japanese is hibachi , I believe — a raised box on four legs. Francis Ow has made a lovely model that looks something like this (diagrammed in his self-published Geometrical Origami ), but the similarity is not structural. For extra credit, you can reckon the volume. It’s easier than you might suspect.

I taught a couple of classes, both on twist folds, and it is too easy to forget that the language used to describe objects with radial symmetry is specialized and manifestly ill-suited to get ideas across. If you don’t fold from different polygons on a regular basis, there seems to be a bewildering multiplicity of landmarks and none of them seem to be the right ones. That goes double for regular polygons with an odd number of sides. My second class was on cutting a nonagon from a square, using angle trisection. (I will recommend Robert Lang’s discussion of the subject as background — it begins on page 34.) I drew up some diagrams for teaching the method I used to get a one-cut nonagon , but they leave out the whys and wherefores. A nonagon has nine sides and interior angles of 140°, which means that we want to fold our square into nine equal slices of 40° each. Because 40° × 9 = 360°, right? Getting to 60° is easy — everyone knows this trick, I should think. Getting to 40° is not quite so easy, but can be done if you bring two points to two lines at the same time. Like this. What you’re doing here is constructing three imaginary, congruent triangles, each one having an angle one-third of the original. And as Mister Coudert taught us all those years ago, “Crass Protestants Can’t Teach Catechism,” which was his allegorical way of expressing the theorem, “Corresponding Parts of Congruent Triangles are Congruent.” It is not a business-like way of speaking, certainly, nor a worldly way, but it does live in the memory better so. (And while we’r...
