I feel like plywood is a really common thing that a lot of people know to have alternating/anisotropic layers of wood grain

  Agreed, that is a great example. That an oriented strand board or OSB.

  Plywood alternates grain patterns at 90° to each other. OSB uses the same technique, but with shredded wood instead of sheets. Neither use the 3D twisting method outlined in the article.
