While designing Scroll of time: 2017, I needed a widget which would allow me to have some square twists on one side of the paper and then to smoothly transition to having the same kind of molecules on the other side. I realized that this widget could be used as a standalone tessellation molecule, so here it is. The name Big and Small Squares says it all. A single molecule is 10×8 grid units (or 5×4 if you only count adjacent mirrored copies as separate molecules), and the whole model is folded from a 32×32 grid. Similarly to Brick and Mortar Tessellation, this can be considered a variation on the subject of Momotani’s Wall.
During collapse, this design takes on interesting shapes, some of which can stand on their own as separate models (see Thermos Bottle for an example).
You can easily spot imperfections in the folding, and tape on the back side which I used to fix the model when the paper tore. This is a big model which hangs on a wall, and I folded it from Fabriano Murillo paper which I had not used before. You can read the whole review in a separate blog post.
