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.
An image I created originally for a board game I'm working on. However I like the lighting in this version better. The original had to be lit well for the game, and the window was dark as the game takes place overnight.
