I just picked one up and was playing around with a few ideas. I was curious what anyone else had done.

I have used mine as a mini seance chamber using the storyline of it being hewn from the last remaining scraps of the Davenports spirit cabinet. I presented it at a home Halloween party a few years ago and got a good reaction with it.
All sorts of manifistations can occur inside of that wooden chamber.

I like that idea. I'm surprised more people haven't but a bizarre twist on the effect.
