This new discovery of mine isn’t really new to me, but I just realized that is represents a kind of whimsical reference that you don’t see in “professional” software very often:
The icon for “cloning” (essentially a special duplication procedure) is a sheep. This is undoubtedly a reference to Dolly who was cloned famously in the late 1990s.
Personally I think it’s clever piece of metaphorage. ;) ;)
