Yes, this is Minecraft. But it's not a recreation of a pop culture icon/giant penis. It's using the game for something really interesting.

This modification to the game is called CivCraft, and to be crudely simplistic, casts you in the role of one of the poor little peons from a game of Civilization, as you team up with other people to build a town.
