Secret Magic Ghost Table

In the play "Blithe Spirit", a ghost shows up during a seance and causes the table to knock, shake, and eventually tip over. An Arduino, pair of X-bees, and the largest servos I've ever seen seemed perfect for the job. The table was also completely constructed from scratch, turning foam on a lathe for the pedestal, to keep the weight to a minimum.

After the production, the electronics were removed, and the table is now part of the office decor in the Executive Director's office.
