You can do some simple animations with gtk. For some widgets in my app
I have panels that slide in and out, or widgets that scroll into view.

I do this by setting a timeout every 50ms or so, and in the timeout
adjusting a widget property such as x position. Here's a widget I made
on top of GtkPane:

   http://vips.svn.sourceforge.net/viewvc/vips/nip2/trunk/src/pane.c?view=markup

this widget sits on the left or the right side of your main window and
slides open and closed with a timeout animation.

The animation is a bit clunky though :-( As Dave said, something like
clutter can make much better animations possible.
