That's funny he's like well first I made a treehouse (shows steaming pile of shit literally made of garbage). Then naturally step 2 is to design and engineer a futuristic spaceship house full of modern tech that blows everyones mind.
There's an artist near me that made a cylinder tower in the 1990s as well, it has a spiral staircase and some weird semi gothic artwork and weird pyramid structures. I hiked here as a teenager.
This is the space ship house I mentioned... More of a dormant mothership really
