Floppy disks are pretty much obsolete by now but there was a time when they were state-of-the-art in personal computer storage, and they live on in the Save icon found in most of today’s applications.
I folded this 3.5” floppy as a test of my newest idea in bitmap tessellations — the Square Interlace Bitmap Tessellation. The rough pixels are made from my Square Interlace Tessellation, with each molecule of the tess (6×6 grid units) representing a 2×2 pixel block. A smooth pixel is made by modifying one quadrant of a molecule.
Folding on this model is not very clean since I was testing how small a grid is still workable. Here, a 32×32 grid was folded from a 21 cm square of Elephant Hide. It’s foldable, but it gets messy, and the smooth pixels, which have many layers of paper, are so thick they wouldn’t lay reasonably flat if it were not for wet folding.
