As me and my 12yr old were putting this together they noticed the bottom of the tree had a unique shape. We had a good conversation about how that symbol means other things to different groups and this is just happenstance and also points the opposite way.
I remember being a child and building a space station (it looked a bit like StarLab so I guess the station in general was on TV or in a book) with a solar array that shape, my parents were a little angry and asked where that shape came from. I didn’t have a clue so I basically just said I liked the symmetry. They told me that’s a "very bad shape and that I have to rebuild it. It ended up being 8-shaped, which was also nice.
