Punchable/stompable switch

Hi, guys. I remember reading somewhere (maybe LMR, maybe Make Magazine?) about a DIY way to make a sort of electrical switch that closed a circuit when it was punched or stomped. It had something to do with a layer of foam between two contacts -- maybe the foam was partially conductive or something? I'm working on a musical project that involves recreating something similar to a DDR dance pad, and I'm trying to figure out how to make the pads. Does anyone know what I'm talking about, and maybe have a link or something? Or does anyone have any ideas that might prove useful? Thanks.

A link from Google showing a few DIY Dance pads.  I think I know what you are talking about, something that someone built for a youth center, but can't find it again. Almost think it was posted here. I've gotten some foot switches from a thrift store, for a robot control, another possible might be guitar pedal switches.
