This is not origami, not as most use the word. Maybe it's modular kirigami. But then, many languages do not make a distinction between 'to fold' and 'to bend'. In this model we will bend paper into cylinders and cones and weave them together into a globe. Borromean refers to the Bruneian property of this model--constructed from 9 linked loops, not one of the loops actually passes through any other. If you are familiar with the 3-circle symbol for the Trinity--or with Ballantine beer--you know the Borromean rings. We're going to cube that in a spherical way. This model will involve cutting with scissors. It will involve glue. It will involve scoffing at purists.
