Charles,

Thanks for your review and discussion of the gif I submitted to the group
for comment.  I know that I was certainly distracted (not to mention,
annoyed) by the radar-like movement of the gif.  If I was distracted, I
can't imagine what some others might be experiencing.

Thanks for pursuing this further with the WCAG group.

Terrie
