Focus uses a mechanism similar to the one I used in
Tapestry but a bit more refined to make it quieter and longer running.
You wind Focus by holding the back wheel in one hand
and turning the front wheel about 20 turns in the clockwise direction.
Release the back wheel and the motion starts with the wheels rotating
in the opposite directions. This continues until one or both wheels
lose momentum and start rocking back and forth. This eventually triggers
the mechanism and the wheels start counter rotating again. The type
of patterns created varies with the somewhat random timing of the mechanism
trigger.
