I was not able to visit the site. I heard that a few other people who had bought it before told me that it looked more like interior design. It's true!
Also, in all the pictures I've received, the GIF comic display is still set to No input.
I've noticed that "Raspberrypi Zero" isn't enough to keep it running in the exhibition, so I had to get a "3B" or "4B". I'll have to rethink the layout and size of the components :-)
