I agree with Kynn that distraction is not inherently evil, but in this case (adding this ad to a content page) feedback seems to indicate that it does cause a problem if not switched off, for people with attention disorders. And yes, it appears that the movement in this is not the same as flicker which is likely to lead to problems for people with photo-sensitive epilepsy. This is mostly based on the discussion of this question on the WCAG list - people can follow that discussion thread in the archives starting at http://lists.w3.org/Archives/Public/w3c-wai-gl/2001JulSep/0123 or when the working group comes to a resolution I will make sure that is sent back as a response in this thread.

Distraction is not always bad. Distraction is merely drawing the user's attention to one specific spot or area, by using motion. Drawing the user's attention is _not_ inherently bad, and in many cases it can function as an aid to accessibility. Be _very_ wary of blanket judgments such as "distraction" (or even "annoyance") equating to "inaccessibility." --Kynn PS: I don't think this violates the "flickering" checkpoint, either. Flickering and motion aren't the same things. -- Charles McCathieNevile http://www.w3.org/People/Charles phone: +61 409 134 136 W3C Web Accessibility Initiative http://www.w3.org/WAI fax: +1 617 258 5999 Location: 21 Mitchell street FOOTSCRAY Vic 3011, Australia (or W3C INRIA, Route des Lucioles, BP 93, 06902 Sophia Antipolis Cedex, France)
