Everything Can Become A Space Ship

As a science fiction fan, I have seen and read enough sci-fi material to know that every shape imaginable can become a design for a space ship.

Here are a few examples that I have come up with in my own artistic explorations. I used low resolution photos of interesting objects and altered the background to look (crudely) like outer space.

Can you tell what these objects actually were before I turned them into hyper-fast spacecrafts?
If I get enough requests, I may share more of these designs. They are fun to make. Also, feel free to share other spaceship designs here; the possibilities are endless.
