Constanze Roitzheim pointed me to this excellent photo by Gerd Laures:
Translation: Caution! Functor! Keep 2m back.

Re: Vorsicht! Funktor!
Constanze explained it to me. It’s a remote-controlled garage door. Funk = radio, Tor = door.
Re: Vorsicht! Funktor!
Ah, thank you! I’ll have to run this past my wife, who speaks German fluently, and see if she knows or figures this out.
Re: Vorsicht! Funktor!
“Tor” is “gate”, not “door”, but, close enough …

Re: Vorsicht! Funktor!
Thanks! It’s a bit odd doing such translations when there are native German speakers about. I guess I could defend myself by saying that in this context, the correct idiomatic translation is door, but frankly I was just wrong.
Torfunk

Sorry, I am reading this only now.
Looking for a left adjoint to your remote control gate?
Try this company: Garagenschwingtore, Schwingtore, Garagensektionaltore, Sektionaltore, Seitensektionaltore, Kipptore, Funktore, elektrische Tore.
Unfortunately they don’t have Seitengaragensektionalfunktore.
But they also offer the Torfunk to control your Funktor.
Re: Torfunk
customer: I need a Funktor on my domain.
Wedding Torbau: Do you now the exact Funktor that you need?
C: It is to be adjoined to the left of another Funktor that I already have.
WT: Oh, you already have one?
C: Yes, I already have a long sequence Funktore.
WT: If you buy an adjoint triple Funktore and get one for free.
C: Hm, but I already have an essentially full domain.
WT: Ah, so will this be your final Funktor?
C: Yes, this should be the terminal Funktor on my domain. There is a limit to it.
WT: Then I recommend a very flat Funktor.
C: That might be natural.
WT: Of course if you took a 2-Funktor, then there would be the option of modifications.
C: Hm, a 2-Funktor would probably be too weak for my needs.

Marvelous!

Re: Vorsicht! Funktor!
Hehe, very nice! An additional amusement for me was that I needed quite some time to get at the actual original meaning - I had thought German was my mother tongue, not category theory, perhaps I was wrong (I wonder about Chomskian views on this) :-)
