: Take care using xinteranimate/xanimate if you have a lot of plots to
: combine. It is very memory consuming and may cause your (small) system's
: X11 to crash. (Did it with a 250 images 500x500 picture on a 32MB
: PowerPC running AIX.) Works fine on a big machine. Another way would be
: to convert your Postscript files using a shell script and gs. Or save as
: a tiff/gif from IDL, whatever. After that use special tools to produce
: GIF-animation (e.g. gifmerge) or MPEGs. This has the advantage of being
: more "exportable".

If they are simple plots, then just plot them. IDL is fast enough to
plot many frames a second of simple graphics. More often you'll need to
slow it down than speed it up. For slightly smoother graphics, maybe
plot to a hidden pixmap and then copy it to the screen window.
