Minecraft players! Have you ever thought to yourself how cool it would be if you could export your creations into a 3d physical model to share with your pencil and paper rpg players? For visualization purposes, wouldn't it be great to hand them a small model of the dungeon, castle, or valley?
Meet Mineways, a free program that allows you to "interactively select a model from a Minecraft world map and render it, or send it to a 3D printer or 3D printing service such as Shapeways." Looks like a lot of potential here... Minecraft modeling is very intuitive - you could easily create your own miniatures. Even cutaway views are possible.
