I'm an author and I am writing a book on harmonic resonance, I need a figure that shows a number of different 3-D Lissajous figures like the one you have, ideally in an array starting simple in the upper-left-near, and getting more complex towards the lower-right-far, to demonstrate the principle of Lissajous figures in 3-D, and to give an idea of the fantastic array of complexity available from this simple concept. I am a programmer myself, and have done Pov-Ray images of my own, but I'd rather not have to reinvent the wheel. Is there a chance you could send me your PovRay source so I could generate the figure I need? In return I will cite your work in the book. (I can't afford to offer royalties, it isn't that kind of book)
