The animation belongs to this thread here http://communities.ptc.com/message/263351#263351
Main goal was to avoid that Mathcad eats up all memory when the animation is made.
Solution seems to be to represent the pic as a plain matrix as opposed to a nested vector.
See the aforementioned discussion for further details and the Mathcad 15 worksheet itself.
Unfortunately this Flash video here is mediocre in quality compared to the original AVI file which Mathcad created.
