SKOTTY DOG TESSELLATION
"Woof. Woof-ruff-woofness. Woofitude." In canine, that means "the theme for this tessellation is Scottish terrier dogs like Benji."
It's a good tessellation because it can completely fill a 2D surface without gaps and without overlaps. As all Escher-style tessellations do, it resembles its theme.
The Paper Cut method KayLee used to make her tessellation can get in the way of refining-editing-tweaking the final dog shape. I mean, the Paper Cut method is a great way to find a shape that tessellates, but although we can easily see KayLee's dogs in this tessellation and it's a good tessellation, the scissors step comes very early in the "paper cut" method, and gets in the way of improving those dogs' shapes to make'em look even more like "Skotty dogs".
That's why I prefer the Tracing Paper methods: the artist can fiddle with the outline by using both ends of the pencil before picking up scissors. It's a harder method, but gives tessellation artists the chance to produce even better art.
This tessellation repeats via the translation (slide) method. That means the dogs are all going in one direction, and nobody's rolling over to "play dead".
This tessellation is a clear example of the "TTTT" type in the Heesch tessellation classification system. That means, each tile touches four other tiles (that's why there are 4 "T"s), and translation (represented by each "T") is the only way they repeat.
