Hi,
Mathematica for PC can save as GIF (when saving a sequence of plots, that
means aGIF (A for animated)). You can use other program (e.g. Animation
Shop) to convert aGIF into AVI.
How to make aGIF under Mathematica? e.g.
MakeAGif[name_String, src_] :=
    (
      SetDirectory["D:\!Users\Borut"];
      Export[name, src, "GIF",
          ConversionOptions -> {
              "Transparency" -> RGBColor[1, 1, 1],
              "Disposal" -> Background,
              "Loop" -> True}
          ] // Timing
      );
I would like to mention the slowness of Mathematica saving sequential GIFs.
Very slow! Why's that?
Mathematic for MAC, as far as I know (I don't posses it), is able to save
animations as MOV (QuickTime).
I heard there are inovative designs engaged for next Mathematica graphics
userface. Is this so?
Well, bye!
