And if you use them in your house, future archeologists could definitely date your ruins to no earlier than 2022/2023. If you had a document and wanted to prevent it from being “backdated” earlier than 2022/2023, you could use the tiling pattern as a background. A geometric time stamp of sorts.
Either that, or it would upend the future understanding of our progress in geometry if you print it with old ink on old stock paper that’s dated substantially earlier than 2022/23.
Very interesting idea! We just have to be sure that these tiles don't already exists in some crystals or materials, in biological creatures, or somewhere else.
Procedural generation in games: Dungeon/Map generation or for combining or creating textures. And you could also used this maybe as an alternative to grid or hexagonal based games.
What makes this stand out is, that you can create larger structures of simple tiles, where repeating patterns and seams between tiles are less visible.
It could be a post-GPT watermark. If a document used this tiling pattern as a (faint) background, you could say definitively that the document was produced in the GPT era and thus might simply be automated babble.
