Jjaro symbol, actually.
The Sci-Fi channel had (is still having, probably) a Twilight Zone marathon tonight, which is cool. When I saw "I Sing The Body Electric," I was surprised to see a symbol that looked a lot like the Jjaro/Thoth symbol. It's on the cover of the chute into which the children drop components – eyes, arms, hair, etc. – to be assembled into a new grandmother.
Sadly, I can't find a picture of the chute, but the resemblance was truly striking, and I imagine those of you here who watched it noticed it too.
The Jjaro symbol I'm talking about is, of course, this one:
The Twilight Zone one had the whole "intersecting rectangles" thing going for it. I'm remembering it facing the other way (with the higher rectangle being in the upper right), but it was still pretty similar.
