Most babies are cute, but I'm not sure that such a statement could be applied to the Lensbaby. It's a rather odd looking affair that takes certain visual cues from a universal joint. Don't be alarmed though, its appearance is integral to its operation. As stated before, adjusting the focal point on a flat plain is the Lensbaby's primary effect.  To accomplish this one simply rotates the front part of the lens in a certain direction. As the front of the lens moves, so does the focal point. . .
