Ask HN: Interesting/geeky home decor projects?

I hesitate to ask because I worry something like this will attract marketers, but are there any interesting home decor projects you've seen?

I saw a fake nixie clock^1 on hackaday that used OLED modules to pretent to be nixie tubes. I've seen some incredibly expensive newspaper e-ink displays^2

Any interesting home decor projects you're aware of?
