  • Is This a Tessellation?

    Webmaster Sethness's Opinion: YES.

    Sure, the birds' necks and chests look a little weird, but that might just be ruffled feathers. Most importantly, I'm looking at the art and I see a repeating pattern without gaps or overlaps. Clearly, that pattern could be repeated forever to fill an infinite 2D plane. I see a little inconsistency close to the center of the picture, where a neck meets a chest, and small inconsistencies where the beaks meet the tails, but these're small and easily corrected errors in the drawing, not in the artist's plan.

    I do that too. Nobody's perfect.
