Vasari. I've just realized some of the Vasari ships resemble creatures. Have anyone noticed this as well? Take the Squirantra, isn't that a squid viewed from top? Take the subverter, isn't that a shrimp? Or the Ravastra? Shrimp-like too. What about the Vulkoras? Even the panel icon looks like a vulture. The Enforcer looks almost like some sort of crab-spider-bug crossbred and the nick-name for the Jarrascul  is sometimes "space-whale". Funny. Take the Serevun... for me it's just a grasshopper. The Karrastra is more like a scorpion and the Jarun is the little roach. Has anyone noticed this as well?

Now for Advent. Lately I've been playing with the free camera-rotating option and discovered some (if not all) of the structures and ships for the Advent are surprisingly upside down! If you look closely at the  Rapture (shown below), which is the best example, and turn it upside down you end up looking at a completely different ship. And it feels right. Look at some of the Advent capitals and tell me if they don't look quite right. The same is for their orbital buildings, with the most resembling noticed on Temple of Hostility/Communion/Harmony.
