Interest in 3D Lissajous Figures lead to a Google search which lead to a free program which ran on the free program, Mathematica Player, from Wolfram research, http://www.wolfram.com/products/player/ From that page, " Mathematica Player is an innovative new take on viewer applications. Rather than just a reader, like Acrobat Reader, or a thin runtime, like Flash Player, Mathematica Player has the full Mathematica engine embedded right there--ready to make documents come alive or to power applets. (Of course, don't forget it can read notebooks too!) Because Player-interactive documents are so easy to make using Mathematica technology, thousands of these are already freely available at the Wolfram Demonstrations Project--with more supplied each day by researchers, educators, students, and professionals.

The free application which graphs damped 3D Lissajous Figures is at: http://demonstrations.wolfram.com/s...3D+Lissajous+Figures+&submit.x=11&submit.y=11 A list of other demonstrations are at: http://demonstrations.wolfram.com/ Enjoy!
