Marble
Clear glass marble from a tabletop fountain. The glass is poor quality and its surface is pretty beat up, so it is not a good lensball, but it is refractive to an extent as you can see. The background is a computer monitor displaying an abstract design made from one of my photos. The marble is 14mm in diameter, and the image is 36 mm wide at the plane of focus. HMM!
