I just received a catalog covering mainly joysticks and trackballs.
Joystick categories {force, displacement} * {finger, hand} operation.
There are also 3-axis joysticks (as well as the usual 2-axis) with
twisting the joystick for the third axis.
There are also varieties of trackballs differing especially in
size (intertia) and resolution (count per ball revolution)..  They
all are labeled "incremental controls".
Included is one block shaped 3-button mouse.
