I wonder if the current poll's results may be skewed as people are clicking on the "no" option because they don't like the feature, not that it is necessarily distracting as the "no" option implies. Personally I don't see how something can distract you from studying if it is on the homepage and does not appear when you are actually studying. The dark blue background was on the homepage and the study page, and therefore I think an argument of distraction had more merit in that case, but this feature really can't be distracting if it isn't even there when you're studying.
That's my two cents. Personally I like the feature. It doesn't really add anything to the learning process but it is kind of neat to look at.
