so now someone is wanting a floating archology.

are there not one or more AA or such that have underwater habitats going?

and there was a anime series recently that was set on a artificial island. Given the creative people behind the series, i found myself speculating that it was set sometime after ghost in the shell.

That is pretty damn awesome.

Misleading title. Those aren't 'ships'.

To avoid someone thinking themselves clever.
