The 91-Wave Atlas: a browser for fractal recursions

Field notes

The project treats the closure condition—signed leg heights summing to one—as the organizing principle for a family of recursive curves. Its stated scope extends beyond the three-leg example into planar figures, terrain, other leg counts, rough interpolation, and signal measurement. The author explicitly separates exact values, measured values, and upper bounds, and anchors the presentation to named results from the fractal-geometry literature. The page also says the material can be saved locally and run offline.
