Hi,
One of the first things I do when I install IE or Firefox is change the settings and add plug-ins to disable GIF and Flash animation. Animation is OK in its place, but I personally find it gets annoying quickly. Take for example the "Stay informed. Subscribe to RSS" Silverlight animation here in the forums. It's a nicely done animation, but having it animate every time I re-enter a Forum has started to wear on me.
It would be nice if I could right click on any Silverlight animation and use the configuration dialog to disable animation everywhere or selectively for that individual one. Eventually there will be 3rd party browser plug-ins that do it, but IMO it would be nice if it was baked into the existing configuration dialog by MS.
Reference articles about "gratuitous animation" and its negative effect on usability:
