Conformable spring-loaded earloops for over-the-ear style headsets are disclosed. The earloop for a headset generally comprises a prehensile member having a connecting member and a stabilizer portion and a ring integrally formed with and extending from the connecting member. The stabilizer portion is adapted to curve at least partially around and behind an ear to clip onto the ear in substantially a first plane. The ring is configured to removably receive and rotatably secure a receiver capsule of a headset therein and to direct the receiver capsule toward a concha of the ear. The prehensile member and the ring define an open-ended curved space to facilitate donning of the earloop. Upon application of an external force, the stabilizer portion is resiliently adjustable relative to the ring out of the first plane toward and away from the ear and / or in the first plane toward and away from the ring. The stabilizer portion returns to a static resting state configuration upon removal of external forces. The stabilizer portion has a larger cross-sectional dimension than the connecting member to facilitate the connecting member in functioning as a hinge for resiliently adjusting the stabilizer portion. The earloop further provides for adjusting the height between a center of the ring and the point along an interior surface of the stabilizer portion that rests upon the apex of the ear when worn. At least some of the inner portion of the stabilizer portion may be an elastomeric material.

A node-link structure is laid out in a space with negative curvature, such as the hyperbolic plane. Nearby relationship data are obtained for an element in the structure, indicating information about nearby node-link relationships; then layout data for the element are obtained, based on the nearby relationship data. The layout data indicate the element's position relative to a parent in the negatively curved space. The layout data can indicate a position displacement and an angle displacement between the parent and the element. The nearby relationship data can be obtained by counting grandchildren of the parent for each child of the parent that is in a set that are being or have been laid out. The counts can be used to obtain a radius and an angle for each child in the set, and the radii and angles can be used to obtain the position displacement and angle displacement. The nearby node-link relationships can thus include only relationships among the parent and its children and grandchildren.
