There have been several projects posted here mimicking the designs from the traditional Japanese Kumiko techniques. One of my favorite YouTubers made a coffee table using those methods (with only a couple of power tools ) which I thought some here might find interesting. The link skips directly to the start of the center design.

Neil scaled it up to make decorative panels to hide a water collection barrel alongside their home. Interesting to see the precision needed for all the pieces to come together perfectly.
