Yesterday’s cell with a horizontal mirror.
One thing that I find fascinating is how many different designs you can make from a single cell. You can vary the rotation pattern, focus on the lines or the shapes made from them, choose colors, and decide which shapes you are going to emphasize in the tessellation. In this one, you can see the original pencil markings from my drawing and how I created a repeating patterns by selectively choosing them to make shapes. Glorious!
