Here's some "translation (slide)" style tessellation art.

That means the basic shapes repeat only by moving in a straight line from one place to another. There is no rotation like a pinwheel nor reflection like a mirror image.

Almost all first-time tessellations, and maybe most tessellations, are done this way. It's easier to visualize than spins or mirror images, and the results can be impressive. After this, try going to Seth's and Dr. David's galleries on this website, and try to count the number of translation (slide) tessellations. How many are translations? How many have spins? How many have flips?
