Top 4 Artificial Levels in Rolling Sky

You might have noticed some Rolling Sky levels seem to be inspired on real-life stuff... Which levels from the game seems to be more based on artificial stuff? I've done a list of the levels for that case, and this is the list of the 4 most "artificial" levels according to my opinion--- i'm not sure if there are more, but i think these ones fit the topic, though i don't know if i'm explaining me well on what i mean with "artificial", as it's not natural stuff but also it isn't purely electrical & modern stuff either
