The Mathematical Association of America (MAA) has developed the Loci site to bring high-quality instructional materials to math educators everywhere. One of their more recent offerings is this article by Michael Grady of Southern Utah University on how to add animations to geometric constructions. The piece talks about how users might use computers and open source ray tracing software to add the dimension of time to their presentations and illustrations. The abstract for the article notes that "The web provides a viable medium for enhancing mathematical presentations with photo-realistic graphics and video." Visitors will note that the piece includes six different sections, including "Projections", "Rotations", and "References".
