This one's Some Old Ideas combined in a potentially interesting

Also am playing with the idea of the "Flip the switch, a hand comes out
of the
box and turns to switch - and goes back in the box" idea for a lidded
box. The lid slowly rises until you can see inside - then quickly
shuts.
A little battery powered motor, a cam and maybe a small finger as the
"push rod".
