Amos - I'm sure that Spartacus wants to build an amplified board for dancing on while playing. Similar to what John Hartford used for many years. I've never built one, but I can tell you that John used a flanger as part of his bag of tricks to get the sounds he did from it.

Other than John, the only other time I've seen one used was by the singer for a rock band called The Chickasaw Mudpuppies. His setup was pretty simple. Just a roughly 3' by 3' box made of 2" by 4"s and plywood. He just wrapped a mic in a towel and put it under the box. He sang while rocking in a wooden rocking chair, playing a zydeco rub-board and stomping on the stomp-box. Wore some big old heavy boots, too.
