This month, I felt like posting one of my really old models, this one made in *checks notes* 2014. This is surely one of the very earliest tessellations I tried making. But surely this was after practicing a few times, because these aren’t exactly a cake walk to make.
Providing a back light for the tessellation illuminates its structure. The tessellation consists of a series of hexagonal twists and triangular twists. Adjacent twists are connected by pleats, which are darker because the light is going through three layers of paper instead of one.
I looked up the symmetry group, and I’m pretty sure this is p6 wallpaper group.
