A new eye-catching featured picture: Kelvin–Helmholtz instability can result from the turbulent mixing of two fluids of different density. It is sometimes observed in cloud formations, on the surface of gas giants such as Saturn, and when wind blows over a water surface. A mathematically generated GIF animation was converted to a video to be much more friendly to slow internet connections at virtually the same quality.

Choice of the week.The Signpost asked FA nominator and reviewer Iridescent to select his best of the week (and of course to dutifully disregard his own nomination). "I chose Silky Sifaka. To me, Wikipedia's great strength is its ability to treat relatively obscure topics with the same thoroughness it gives to the major topics. Readers can find equally good articles on major subjects elsewhere; but there's probably no other free resource which covers this particular species so thoroughly. With its combination of well-written prose neither over-technical nor dumbed-down, thoughtfully chosen images, and informative sound and video clips, this article is Wikipedia at its best."

The entire list is well-referenced and well-illustrated by relevant images."

Choice of the week. We asked Makeemlighter, a regular reviewer and closer at featured pictures candidates, to choose his favorite among the past week's promotions: "With several outstanding images this week, it was a difficult choice. I kept coming back to the Freiburg panorama, so I'll make it my pick. This panorama is very sharp and well-stitched. As an American living in a suburban neighborhood, it's fascinating to see such a detailed image of this German city. I really get a great sense of what it must be like to live in Freiburg. It's particularly interesting to see the modern layout of a city that's been around since the 12th century. Be sure to check it out using the 360° viewer. " (below)
Featured picture Choice of the week: a panoramic view of Freiburg, Germany as seen from Schlossberg. Freiburg Münster (cathedral) can be seen in the center.
