A hand-held amusement device has a variety of features that encourage manipulative activities in and/or by a person's hand. These features may include various combinations of a base that is configured for rocking back and forth on a support surface; a cylinder that rotates relative to the base; a plunger that telescopes relative to the base; a clip that slides back and forth on the base; a lever that pivots back and forth on the base; a hole that extends through an end of the base to facilitate twirling of the device about a finger; at least one word embossed in braille on the base; and a spherical ball that is rotatably mounted in the base and protrudes outward from the base. The base may also be configured for rotation about three orthogonal axes while supported in respective positions between a person's thumb and an opposing finger.
