Some aliens and fantasy races really like to make vehicles, armor, weapons, and architecture that resemble themselves, whether its insectoid aliens building multi-legged crawling war machines or mermaids that have a fish-scale pattern on all of their clothing. The human version is probably mecha, but this goes a little further and has less logical explanations, and seems mostly for aesthetic reasons. Not to be confused with organic tech or living ship, since those have a reason to resemble their creators or some other life-form.
