Duh -- now I remember what I was going to do with animate
when I had more time. Just use javascript! Javascript
is great at animating a sequence of images, scratching through,
changing the speed, etc. So, who can find a good free
javascript script to do this somewhere online, which we can
touch up for inclusion in sage?
