I might be wrong (and that has happened often) but I was under the impression that animation was fine if it could be turned off? In studies that I have seen by agencies that work with dyslexics, they actually like animations and they are a large proportion of the disabled community (numbering 5 million in the UK alone).

I think some clarification is needed.

Not all animation causes flickering of the screen.  Images that rotate
quickly might, and should be avoided, but certainly not a smooth transition,
such as you are capable of with Flash animations (but that's another topic
altogether regarding accessibility).
