SU has got this thing about shapes. They’re important. So its interesting to me that the moonbase has a pentagonal door

and the temple has a pentagon over the door (it also has a similar striped pattern along the sides as the moonbase has on the floor in front of the door)

know what else has a pentagon on it?

and consider how the Kindergarten control room is a hexagon

as are the injector’s tops

just like Amethyst’s gem

so there’s a precedent of a relation between gem cuts and the shapes of Gem things.

Also, while I’m rambling, I always found the moon looking symbol above the temple door curious, since there’s never any attention called to it but its a huge ‘blank’ space while much of the other space has more intricate geometric symbols. So it seems to specifically be something/representative of something. Maybe…

I dunno
