I was hoping to write PPMs a while ago, but OS X's Preview doesn't seem
to support it.

Yeah, I don't think preview does. Graphic Converter does though.
It's what I used to make the movie. I bet you can also get netpbm
installed on OS X, then you can just shell out to those programs to
convert the images or build a movie.

Talking about netpbm, I used it from Linux and I had no problem to
create an mpeg from 705 frames (512x512) only that err... it is about
50 times too big.
> 30MB
No way to post this to the list, I continue to try making it smaller -
this is my first attempt of video compression.

Would you be interested in it for the site maybe, and if so what size
is acceptable?
~ 10MB?

So if someone wants the configuration file for ppmtompeg I can post
it(1), maybe we will get some help to make the files smaller too?
Cheers
Robert

I'm going to pass just because I already have one movie up there and
I'm sure that's doing enough damage to my alloted bandwidth already. ;)

Oh not "better." More just a poor man's RMagick. ;)

Well, for *very* simple graphics at least. RMagick does a LOT more.
