A variation on useless machines. A small geared motor rotates CW or CCW depending on the position of the switch.
Creepy hand https://www.thingiverse.com/thing:1524972 is scaled down to 60% and printed twice. One of them is mirrored to get a left and a right hand.
For printing, the centerpiece is rotated along the X-axis over 180 degrees. In this way, no support is required. The hands are bonded to the centerpiece.
Print the ball flat side down (no brim or support).
