PURR HAPPY KITTY
by Hannah S.
This tessellation shows translational (glide, slide) symmetry.
The cat-shaped "tile" (tile = repeating shape in a tessellation) is very neatly, precisely reproduced and fits with all the other tiles perfectly, without gaps or overlaps. That's what a proper tessellation does.
However, it's a little hard to recognize the cat shape here. Did they get smooshed by a bigger cat? In most first-time tessellation art, I wish that the artists had taken time to tweak the "tile" outline to make it more nearly look like the theme, in this case "cats".
