Here's a wonder for you: These are skeletons of Cyrtoidea, a kind of radiolarian. They're among the tiny creatures that make up plankton, at the foundation of all life in the sea.
The illustration is by Victorian naturalist Ernst Haeckel, and is one of many gorgeous plates now in the public domain. (I snagged this one from Wikipedia.)
I don't know which is more awe-inspiring, the drawings themselves or the fact that these structures belong to real, living beings that share the planet with us.
Sometimes, you just have to sit quietly and soak up the magic.
