FACE THE CASTLE
by Trenton H.

This tessellation shows translational (slide) symmetry.

The "tile" (tile = repeating shape) is exactly reproduced and fits with all the other tiles perfectly, without gaps or overlaps. That's what a proper tessellation does.

If I offer any constructive criticism, it's this: I wish the artist had tweaked the outlines so that the base of each castle would look more like ground-- grass, a moat, or something like that..
