A computerized method operable on a computer system for compositing data streams to generate a playable composite stream includes receiving a plurality of independent data streams that are included in a broadcast stream. The first and second inboard wing sections rotate about a centerline hinge, and a centerline spring applies force to the first and second inboard wing sections to rotate the first and second inboard wing sections from a stowed position to a deployed position. Through the use of a method and apparatus in accordance with the present invention, a user will be able to perform therapeutic hand exercises without the complications of existing therapeutic devices. In one embodiment, the porous antifuse dielectric layer includes SiO2 formed with air-filled voids.
