My husband helped me with this one. I asked him to pick out a picture from one of the little Golden books on the Solar System and he came up with this illustration of two planets orbiting each other. It represents a couple of key concepts I like to operate with, first that both of us are constantly orbiting around each other and there is a sweet simple effect as a result which is represented through the on-land portion of this card. A second concept is the idea that planets orbiting, rain falling, and trees growing will go on endlessly. I know there is a lot of fear that it isn't true but taking into account the whole timeline of our solar system, earth, and the human race I think it is silly to think that it will all go down any time soon.
There are several other ATC's here for your veiwing pleasure.
