If you want it real simple. Use a fish caster reel with fishing line(you will not see it). Attach a reversible motor relay to it. Run that motor off a 9v battery(no wires, easy to mount). This will provide the up down movement. Create a small platform and mount a second motor to the center. Attach the 9v motor to the end of the platform so it gets good circular rotation. Then attach that platform motor to the ceiling.
You will need two voltage adjusters to slow down both movements since both voltages are different.
