Here's two views of the finished ark, with a few animals. Perhaps you can see how much fun I can have designing on the fly. The door in the hull opens down and becomes kind of a ramp. When not being played with, the animals can be stored in the hull. The roof with the leather hinges opens up, and there is one of the other side too.
I don't know what the next Noah's Ark will be. If there is any suggestions as to design, or colors, or anything else; feel free to leave a suggestion in the comments.
