This shape is always possible to create. It doesn’t matter where white moves.
I did it in the last 200 games.
At first this 13x13 fuseki is not very effective. But then I have much more experience than my opponents. I usually able to capture all stones that invade my base.
Yes, I may be a pedant (though not the only one for sure) and I can’t force anyone to like me. But I do put my shapes where my mouth is.
I proudly present the stable bomber:
This one was surprising to me. I expect to attack with a hane on the first row, but that doesn’t work here. I’ll call it “the portcullis”:
I didn’t really believe it and had to wait for the end of the game to verify with the AI review that it actually made sense.
Only 14. Plenty of space to improve on that.
Double B2 bombers flying in wing-to-wing formation
Parallelogram (almost square)
Update on this.
I never see the vase. It’s not worth naming, imo.
The opposite is true of the jug: now that I’ve recognised it, I see it very often and I now regularly refer to it in my mental dialogue.
For reference:
The X points usually host hostile stones.
I heard a french player say it in a stream yesterday, and as @mekriff says, Inseong Hwang calls the shape a scorpion shape in 3-3 invasion type joseki.
The first two are from playing 3-3 point openings and the opponent letting me get an outside hane (kind of big and mini scorpions 
)
The 3rd one is more properly from a 3-3 invasion where much later I was chancing my arm trying to live, and the atari was not the right move in this case.
Somehow, this shape rather reminds me of something different. 
I heard Mathieu Delli-Zotti, a french go federation teacher, call it scorpion shape too. Very resourceful, it is often played since AI - was it used before? I wonder if it has a different name in Chinese and Japanese? 
A few days ago, I made my first B2 bomber (as far as I’m aware).
Not B2 bombers but some other planes or spaceships flying in formation?
Definitely from space invaders!
I think it’s Galaga:
@okonomichiyaki’s shape could also be called a “Y-wing” (from Star Wars)
Not mine, but I spotted this fish in the wild
Depicted with @pdg137’s solarized color-scheme
So cute! 
Oh, I only see the fish now it’s in the blue scheme!
White found a cool tesuji to capture one stone:
Luckily for me (black), white can’t live inside even with that capture 
The triangle marked stones are “the question mark”
Update: I continue to see both the crocodile’s mouth and the jug shape commonly at all levels from 9k to professional games.
