arXiv Abstract 1907.08433

Animations created by Origami Simulator of the two polycubes that have no edge-unzipping. These animations show edge-unfoldings (but not unzippings). Each animation is a .gif file, on this page reduced to 800 pixels wide (the originals are about 1200 pixels wide).

Here are the two .svg files of the unfolding layouts, with edges colored so that they can be imported into the simulator.
