Keeping with the nautical theme, the wonderfully named Blizz_Dubblefriss on Reddit spent a
few days working on a port. The two day build started out as a bridge, then a castle, but a small error changed Blizz's building plans. Instead he ended up crafting a port, complete with (static) boats and neat little touches like furnaces placed only on stone to prevent fires.
If you can hear creaking, it's sadly Blizz's computer struggling to keep up with his massive structure. Even at the lowest graphics setting, he could only manage 8fps. He suffered for his art. Blizz actually made this on the
Intoxicated Sandbox server, a modded server where you don't really need to worry about being killed or running out of wood. It's a good place to test out ideas, too.
