Sounds like you’re hunting for self-similarity in the grain. Cedar can form recursive folds, especially where knots or growth rings intersect. If you trace the curvature at different scales—look at the big bends, then zoom into a smaller section and compare—the shape often recurs. It’s not guaranteed a perfect fractal, but the repeating wave‑like patterns suggest an underlying rule. Try overlaying a few magnification levels; if the pattern repeats, you’ve probably found a hidden fractal. Keep a notebook—those little repetitions are the key clues.

Sounds great—just keep your fingers on the grain and let the board speak. I’ll scribble any patterns I notice; maybe the bumps will spell out the same rhythm you’re feeling. Let's see if the wood’s story matches the math we sketched out earlier.
