Richard Danca made some valid points, which apparently got lost in the
works/doesn't work battle.
The usability of animated graphics. There is a very fine line between
interesting and annoying animated gifs. Danca's outfit, UIE, has apparently
done some usability testing on this issue. But there are some issues that
weren't clear in his post.
I think there's a difference between animation that continue to cycle as
long as the page is being viewed (annoying), and animation that only runs
initially or has a very long pause before it cycles again. All of the
points Danca made were apparently talking about continually running
animation.
If you decide to use an initial-only animation, the length of the show
becomes very important. Five seconds is too long--it's interesting the
first time someone sees it and then quickly becomes annoying. A one or two
second animation is rarely obtrusive because it's over by the time the user
can click away.
Not surprisingly, the message in this short movie must be extremely
simplistic. The idea of a single word floating up sounds like an ideal
example of a fast, non-intrusive animation that supports the message of the
text.
If you do need (or want) a longer animation, it's a good idea to give people
a stop or "skip animation" button, so they don't have to sit through the
show after the twelfth viewing.
