The University I work at shuts down for about a week each Christmas. I knew I wanted to try something big and complex over the break and eventually settled on a large Doctor Who Tardis.
Let's roll back to DragonCon 2019. We decided to go for a day. Later in the day we found our way to the gigantic dealer room. I met an artist who specializes in stained glass and stained glass styled window clingers. I immediately bought the window cling version of his Tardis. It's even on my window at work, so I see it every day.
