No it looks like an Ouija board. /s

Well you can look at earlier forms of this kanji on Wikipedia and other sites. It was just supposed to depict a big spoon originally. Over time kanji forms get refined/simplified, and meanings transform. Though the meaning here is still pretty much the original one, just that people have started imagining a big spoon in the sky apparently. When? Dunno, but there's already a reference in Odes (Shijing) which is pretty old https://zh.wikisource.org/zh-hant/詩經/大東

維南有箕，不可以簸揚。維北有斗，不可以挹酒漿。
維南有箕，載翕其舌。維北有斗，西柄之揭。
"In the North they have a dipper, but it cannot be used to serve alcohol." (as it refers to the stars)
