Some of the people still not realizing that Google dance don't exist any more.
When Google introduced Google caffeine, new hardware infrastructure and new search engine algorithm they speed up finding and indexing new content and all that stuff is going on in back stage all the time, so there is no more "static" results which are dancing from time to time, they may appear like static right now, but google is constantly runing in the background, trying to give best possible search results to the end user.
