  • Is This a Tessellation?

    Webmaster Sethness's Opinion: Yes and no.

    In the lower left half of the photo, definitely "YES" because the feathers fit together without gaps or overlaps and clearly, that pattern could be repeated forever to fill an infinite 2D plane. However, in the upper right half of the photo, many of the feathers are overlapping. The "tiles" in a tessellation shouldn't overlap. So, in the upper-right area, "NO".
