I made one.
We built it out of 2x4s.
I added 2 Large Electrodes that I mad out of plastic bowls and champagne glasses.
I put a bed vibrator under the seat and had a fog machine send fog up through the bottom of the chair.
I also took a couple of small waste baskets added electrodes and wiring so the looked like small transformers.
On each waste basket I attached to the top a small luminglass.
All activated on Remote
