Well, I for one thought that was the most useful post on this thread,
and have saved it in my good advice folder.
Also note that if you use a portable format then you can incorporate the
resulting movie in an Open Office presentation, and then export the
presentation as a powerpoint and the movie will still work. I make all
my presentations in Open Office. It might even work on powerpoint on a
Mac (although I have sometimes found that compatibility between OOo and
MS Office is better than compatibility between MS Office and MS Office).
In fact, I have a suspicion that OOo re-encodes movies, so you may get
away with making all your movies as (huge) animated gifs using 'convert
*.png movie.gif' and then importing it to OOo. Has anyone else tried this?
The mplayer package can do some other neat tricks. But I'll let you
visit http://www.mplayerhq.hu/ to find out the essentials.

Since the topic of making movies has been raised, I have to chip in.
Most graphics programs can create a sequence of frames that, when combined
together, show a rotating object. However, the procedure of combining these
frames into a movie is problematic for people who are not aware of the
ridiculously fast and free program called "mencoder", which is a part of
MPlayer. Mencoder runs in linux, windows and osx:
http://www.mplayerhq.hu/homepage/design7/news.html
Here is a command line that takes all PNG files in a directory and puts them
together into an AVI file:
mencoder "mf://*.png" -mf fps=25 -o output.avi -ovc lavc -lavcopts
vcodec=msmpeg4:vbitrate=9000
the important and variable switches used:
fps - frames per second
vcodec=msmpeg - Microsoft MPEG-4 codec (playable with "Windows-native" codec
on all windows machines, as opposed to vcodec=mpeg, which is a DivX codec and
requires installation of DivX)
vbitrate=9000 (9 kB per sec - high quality movie, can be increased or
decreased)
If you decide to install the entire MPlayer package, the resulting movie can
be played using mplayer.
