Here are some examples of pictures I want to use for the sides of my planet cubes.

The larger outer-ring planets don't have pictures of their surfaces, and I don't want a picture of the whole planet.

Another idea I was thinking of making cubes of all the same size, and put pictures of animals and plants on them and then put them in a boggle cube, and it could be like "create your own ecosystem" much like that Spore game Troy is always obsessing over. The boggle cube could be earth and you can chose what animals you want on it. I'll be sure to include dinosaurs too.
