Ahh another classic is reborn. Check out this cool project where you can make the classic “Head in a Crystal Ball”. Of course not only does it move it also talks and floats as well. Here is a description from the original Disney concept:

“Resting inside the crystal ball is the ghoulish disembodied head of Madame Leota, the house’s resident medium. Her hair is long and white, uncombed, her face a ghoulish yellow-green, and she looks around the room and moves her entire face in a rather animated way (for a ghost at least!) “
