Lets Make Some Greeblies

I only know what one of these contraptions is and at this point I have know idea how I might use them. The miniatures were slapped together using bits of leftover plastics, mostly! I have wanted to get to this project for some time and all I needed was an excuse to get down to my shop. The greeble in the center is a miniature desalination unit. I have another greeble on my workbench waiting on some plastic putty. I will post this as soon as the piece is completed. Remember, you can never have too many greeble.
