1. A gear, comprising:
(a) a circular base having a front surface that includes an inner region and an outer region that surrounds the inner region, the circular base being rotatable about a central axis, and
(b) a plurality of gear teeth arranged in a same row and extending outward from the outer region of the front surface and being evenly spaced from each other along a plurality of locations on the outer region of the front surface, each gear tooth having a cross-sectional width that varies with decreasing distance from the central axis of the gear in a manner that, and having an outer shape configured in a manner that together permit any one of the ear teeth in the row of ear teeth to contact and directly mesh with an one of the gear teeth in a corresponding row of gear teeth of a substantially identical gear for any gear angle within a predefined range of gear angles between the central axis of the ear and the central axis of the substantially identical gear; wherein
(c) the outer shape of each gear tooth of the plurality of gear teeth is defined by independently rotating each one of a plurality of locations on a starting profile associated with that gear tooth, the starting profile being initially disposed in a reference plane that is perpendicular to the central axis of the circular base and extending outward from the central axis of the circular base.
