Repetition in the woodshop can be boring and thus dangerous, but one silver lining is a batch of identical cut-offs. In the course of making a series of benches, I cut the tenons for 16 legs on the table saw, which yielded a pile of squares and rectangles I couldn't bring myself to throw out.
I also saved the cut-offs from the leg tapers, for an as-yet unimagined future project
I used an aerosol spray-on poly to get in all the gaps, and for its fast dry-time
in the spirit of non-functionality I didn't measure, either for spacing or square. I applied the tiles using rub joints, which is to say I glued them on
minimal sanding to preserve the tool marks... and because there were 60+ tiles
it took a surprising amount of time to land on this arrangement. I tried to avoid repeating combinations and uninterrupted gap lines
