There are a few patterns in this, actually. The cross isn't really in that pattern, but the "center" (the black part) is what the world looked like before it existed. Red, God created the sea.. each color brings forth one more element that He created on each day, and it goes on to the end of the picture. The rainbow pattern.. a rather elementary concept that would probably not be understood without explanation~ God promised to never flood the Earth again. Another thing that probably needs some explanation is the pattern of dark and light in there.. that's actually supposed to be along with the pattern of creation. God created light on the first day.
