The more animal-looking DS9 ones? Yeah, they're pretty cool! I'm very fond of the humans-with-something-glued-to-their-foreheads designs, but I liked seeing more differences, especially when it can affect their behaviour/perception/abilities :)
Yeah, lots of people had their own take on it but I think a Tumblr user named engingerboom/subspacecommunication posted more of it than anyone else. That blog is private or something now. Lots of Garak and Bashir fanart came out of that too.
Thank you so much, noted.
