Here's a link to one of the originals that I used to generate the 3-d analglyph . . .

Excellent find! Maybe this explains why many of the spheres have a small hole - that would be the spherules' 'belly button'.

Of course, bizarre morphologies will be attributed to tricks of lighting and perspective. /sarcasm

And another! What's that thing hidden behind and under the ball with the flat top?

I found it. They didn't rearrange it, but there are multiple sites. Some of the micrographs make the spheres look kind of "fuzzy". Maybe some kinda fungus.
