I haven't explained this well at all.  There is a little pot that has a copper pad on the base that is divided into 4, there is a non-conductive divide down the middle.  If you put resistors in one half and capacitors in the other then jiggle the pot you will get random varying resistances and capacitances between the pads of each pair.  These could be used to make freaky filters.  The speaker can jiggle the pot and make a nice shakey sound.
