Another Origami Handbag

The “manhole bag,” another of Ms. Tsukioka’s inventions, is a purse that can hide your valuables by unfolding to look like a round sewer cover. These ideas might strike foreigners as far-fetched,” Ms. Tsukioka said, “but in Japan, they can become reality.” From today’s NYT. An interesting article, but it doesn’t mention that the Talking […]

Stellated Curved Tetrahedron Redux

Stellated Curved Tetrahedron Colored Crease Pattern Some people there may be who haven’t folded this yet and still want to. The clues we left were not the easiest to follow. Here is a colored crease pattern: black for mountain, magenta for valley, gray ghost lines for folds that were there, but don’t figure into the […]
