The night of the witches is coming: we need thus to gear up with a suitable decoration, so to create an atmosphere worthy of this celebration.
For this circumstance there are many suggestions on the Internet, and specially creations made with 3D printers; among those available on the popular website Thingiverse, we chose a “dynamic” decoration, that is to say a pumpkin that automatically opens and closes its mouth. Inside of it there are some ghosts that move over and over again.
