What's a Lensbaby? From Wikipedia:
Lensbaby manufactures a line of camera lenses that combine a simple lens with a bellows or ball and socket mechanism for use in special-effect photography, allowing modern cameras to obtain effects associated with view cameras.
Lensbaby lenses can be used on cameras that accept interchangeable lenses, mainly of the 35 mm or digital SLR formats. The focal length of the Lensbaby is approximately 50 mm, making it a normal lens in 35 mm format[2]. The front standard can be manipulated off axis to move the sharpest area of focus (called the "sweet spot") to almost anywhere in the frame. Therefore the important part of the subject can be rendered fairly sharp with everything else out of focus, even if it is the same distance from the camera. Aperture is controlled by a series of interchangeable discs (basically a Waterhouse stop).
