>From an accessibility point of view, a single switch that turns off all animations would probably be useful, for some (not necessarily clear to me) definition of "all animations". Thin clients like Sun Ray also need a way to turn off anything that's going to send lots of unnecessary display traffic over the wire, which includes "all animations" plus a bunch of other things (such as using images for your desktop background). Categorisation by utility might be one approach, another might be categorisation by animation frequency-- either "don't animate anything at more/less than x frames per second", or "switch off anything that might animate at fewer than x or more than y frames per second". Section 508 guidelines suggest that nothing on screen should animate at a rate between 2 and 55 frames per second, for example, to avoid inducing seizures in susceptible users.
