As it's almost Halloween, a little project (and subsequent thread) necromancy seems in order. I've had time while waiting for switches and other things to come in, so I made some new prototypes utilizing ball bearings and made the cover facades removable.   I've minimized the footprint to the best of my ability.  No idea on what it would cost to mass produce, and frankly I'm not sure I want to deal with another production project yet either.  But here it is nonetheless.
