This is great!!! Diatoms are one of those cool little facets of nature that I would hazard most people don't know about.

My favorite images of them are from electron microscopes. They look like biological crystals or something.

I used to have a link to a collection of them but can't find it. Yes this is a pinterest link lol

While you're at it, check out snowflakes under a SEM.
