Hi,

I made a really simple extension for doing layer-by-layer animation using Inkscape. Check it out here:

If someone could post this on the Inkscape-users mailing list I'd be much obliged.

Hmmm, it won't work for me. Is it because I have Vista? Could you explain how we prepare things to be animated. I mean, do we need to have stuff selected and on different layers or what?

That's a very interesting way to make animations. Congratulations. A while back Aho recommended AnimEasy but it only works with Linux. I'm sure that you are happy with your own extension but in case you are interested then check out this thread.
