Fortress (2007)

 
I find it hard to believe that I only ever took one picture of this, but unfortunately that's all I have. The fortress has two peripheral creations, a small, magnetically and vertically docked ship, and an even smaller white and gray ship, both on the left. You can see part of it on the bottom right, but the actual NXT-controlled spring cannon I believe was there isn't in the picture.
