All versions of Mathematica are able to display sequences of graphics
as animations. The details vary on different platforms.
The following command will generate a sequence of graphics:
Table[ Plot[ Sin[ a x], {x, 0, 10}], {a, 1, 6}]
In any version of Mathematica with a notebook front end double
clicking on one of the resulting graphics will run the animation.
On the Macintosh you can save the entire animation as a
QuickTime movie by selecting the cell bracket that groups the
animation and then selecting "Convert to QuickTime" from the
Graph menu.
If you are running a version of Mathematica without a notebook
front end you will want to use the Graphics`Animation` package
which is documented in the "Guide to Standard Mathematica
Packages Technical Report".
I hope this helps.
