Wish the fruits of your labor in Minecraft existed outside the computer screen. Now there is a way to make your creations tangible. Shapeways, a company that specializes in printing 3D objects (think Spread Shirt for paper-crafts) allows you to print out your characters, structures, and for the right price, even worlds.
The open source Mineways program, by Eric Haines, allows you to pick a chunk of your Minecraft world and export it in a format suitable for sending directly to a 3D printer. You can also choose to edit the model using 3D modelling software, such as Blender, prior to printing.
I hope you can print out ducks!
