My devotees have to get their own accessories. At some slight mark
up ;-)

One project was a free-floating joystick. A ball bearing moved in
a cross-shaped enclosure. The bottom of this enclosure was a cross-
shaped piece of copper. This was the common terminal. At the end
of each arm was a copper terminal. The ball bearing shorted the
common to a terminal, depending on which way the joystick was
tilted. The other project was a ball bearing clock. Minute balls were
powder coated black, the hour balls were gold
