ScrumbleShip is the most accurate space combat simulation devised to date. Gather resources, construct a capital ship out of individual blocks, then pilot it with AI or human help against other players.

I'm not sure who built this, but they've been working on it when I wasn't looking. Looks a lot like a face, from this angle.
The interior is particularly neat - Somewhat spacious, with lots of fun doodads along the walls. Because of this, I've been using its interior as sort of a benchmark for the graphical improvements I've been working on. Helps make sure the graphical improvements help inside a ship as much as outside a ship.
