If you back out far enough to see some of the shape the atoms are forming, you are too far away to see them. So I made them reflect a common tree. And like looking at shapes in the clouds, it's easy to see things in the tree as well.

Bryce 5's trees refused to work the way I wanted, so I used complex models in the solid glass spheres instead. This turned out to be a mistake. Due to the intense reflection depth rendering, this took a week to render.

Creating this many pillars individually would have been impossibly complex. I instead made a solid block, with a grid of negative cylinders inside, carving out the archways.
