I ran the simulation and I was asked, in text, if I would like to add something into a layered image, as it would have contributions from various attendees.
In text, I said that I was adding a symbol that means Welcome in any language and a curator approached and asked if it could be used in a display. And, in text, I added the Thank you for visiting symbol. Then I used ARCH and asked Copliot if Copilot could produce illustrations if I uploaded the designs. In the event, there were various attempts and reuploads and the Welcome one, bright with a picture of mountains got the symbol mangled. But the Thank you for visiting one is nice.
Here is the symbol that I uploaded and the picture that Copliot generated.


It is rather dark but there are people watching a display on a screen.
However, the fact that it will do it at all is amazing.
