These features appear ubiquitously in the quiet sun. They are co-spatial with reversed granulation, and display similar general properties, but have sharper edges and show fast brightness changes. They also appear predominantly above wide intergranular lanes, indicating a potential connection with magnetism. We report on the appearance and dynamics of these features using high-resolution, high-cadence observations from Hinode, and we discuss their possible origin.4 pages, 1 figure, proceedings of the Second Hinode Science Meeting, held in Boulder, CO, Sept 30 - Oct 3, 2008Solar and Stellar Astrophysicstext
