I just had a thought about how it's weird that all fictional hive-minds generally still have some queen or overlord
or other building-sized entity. How about a hive-mind with no social ranking whatsoever? Just a bunch of (cute) drones wandering about contently building some giant city somewhere or something?

The only problem I can think of is when they get a phone call and the person on the other end asks for the one in charge.
