A long time ago I found a small, hexagonal piece of paper laying around my house. I do not know where it originally came from. Ideas include a Chinese language camp I attended several years back, although this doesn’t really look like a Chinese character to me. I have not found anything else similar.

PICTURE. I have included a few different rotations of the image, because I do not know which side is up.

Can anyone recognize what this is? Or, is it just nonsense?
