Leonardo, a journal that focuses on applications of science and technology in art, included this paper in its second-to-last issue of 2002. The author discusses a fascinating method of creating three dimensional shapes in a semi-immersive virtual environment. Developed at Caltech, the technique tracks the motion of a user's hand, which is fitted with a special type of glove. With the help of an eyepiece viewing device, the user can see the corresponding surface drawing floating in midair. Several pictures of the system and objects created with it are shown. The paper illustrates the system's ease of use and its multitude of uses, even for non-art related purposes.
