It's interesting that in both of the examples people have shared here, the image produced was quite good but entirely missed the "flowing out of the building" part of the prompt (which I think is a fairly significant aspect of the scene).

I picked the one that most included that; a few other suggestions didn’t have water at all.

Wow, existing text-adventure could be very interesting with this kind of semi real-time illustrations. Maybe we'll finally know what is Grue like. Also, Table RPGs with Dall-E illustrations generated semi-realtime by the game master.

That was surprisingly good.
