[pstricks] Generation of an animated output file from pure graphics

  Manual Luque (who is the kind of person who has three new, original and
brightful ideas each day: his Web pages are full of innovative and beautiful
examples -see http://members.aol.com/Mluque5130 ) recently write a code to
build some pictures of waves interferences. His code is very short, but
nevertheless produce very impressive results. After doing it, he would like
to build some animated file, showing the evolution of the physical phenomena.

  By itself, this is easy to automatize. As these graphics are "pure",
we can use the \PSTtoEPS macro (pages 80 and 81 of the documentation)
to produce an EPS file for each image.

  Then to produce a file of the animated GIF format (I suppose that it must be
possible too to use the MNG format) we must convert each EPS file in a GIF one
then to mix them together.

  Under Linux, I know to do it easily, using a shell script, ImageMagick
and gifsicle for instance. But this does not help Manuel, who use
Dos/Windows, that I never use myself. Does anybody know how to do the same
in an automated way under this operating system? The shell script must be
converted and it must be known if it is necessary to install ImageMagick and
gifsicle (I know that some Windows ports are available), or if a better
way exist. Thanks for him.

  I put the resulting file on

and attach the source file from Manuel and my Linux script.
