Yeah. That'd be inbetween Cruiser and Destroyer size stuff. If I can drudge up more, I'll certainly add in that faction in later games. Gotta build it first, though. As I recall, the Will-O-Wisp took me about a week of puzzling.
I'll try to take better pics, just to show you some details. once you see the inner workings of that "head" piece (with the red translucent stud and dark gray circle piece) you might understand why it took so long.
