Abstract: The invention provides systems and methods for a writing instrument that can be manipulated into an infinite number of shapes and configurations. The invention can be applied to relieve minor stress as well as strengthen hand muscles, rehabilitate finger and joint movement, and improve overall range of hand motion. A textured coating can be applied to the surface of each segment that gives the writing instrument a unique feel, thereby creating a pleasant sensation and feel to the hands and fingers. Segments can operate as a holder for a writing instrument body, and similarly can be arranged to provide a creative sculpture. Segments can be removed as desired by the user.

Abstract: The invention provides systems and methods for a textured therapeutic toy that can be manipulated into an infinite number of shapes and configurations. The invention is best applied to relieve minor stress as well as strengthen hand muscles, rehabilitate finger and joint movement and improve overall range of hand motion. In one exemplary embodiment, a textured coating is applied to the surface of each segment that gives the therapeutic toy a unique feel, thereby creating a pleasant sensation and feel to the hands and fingers.

Abstract: A method of simulating real-life motion of a character includes providing a toy having a plurality of interconnected links. The links are rotatably attached to one another and the character is attached to one of the links. The method also includes grasping the toy by holding two different links that are separated by at least two other links, one of which is the link to which the character is attached. The method also includes moving the hands with respect to one another, thus causing the character to move in a manner that simulates the real-life motion of the character.

Abstract: An annular support device is formed by a series of identical torus segments with adjacent segments connected end-to-end in a continuous loop. One end face of each segment has a central channel for receiving the extension of the adjacent torus segment. The extension-channel interface between adjacent segments defines a twisting axis permitting each segment to be twisted through 360 degrees relative to the other segments. The support device may be twisted into an infinite variety of decorative and useful configurations. Each end face has a raised peripheral rim which abuts with an identical cooperating peripheral rim on the opposed face of the adjacent segment. The rims are circular and define a common interface plane perpendicular to the twist axis therebetween. The torus curve causes the twist axis at each end of a segment to be non-aligned, and prevents individual segments from being twisted relative to both adjacent segments simultaneously.
