The Flying Piranha And Imperial Fort

No this isn't an official set, but it has the feel of one, and it's intentional. Legonardo Davidy and Cara have combined efforts for the Eurobricks Pirate Teamwork Contest and the results are stunning. The design of both the ship and the fort are brilliant, with wonderful play features and detail rivaling that of real LEGO designers. There's tons of pictures of both these models and some great making of shots, click through to explore.
