Galactic Currents
A video map of motions in the nearby universe
Map showing all galaxies in the local universe color-coded by their distance to us: blue galaxies are the closest, and red are farther, up to 300 million light-years away.
(Phys.org) —An international team of researchers, including University of Hawaii at Manoa astronomer Brent Tully, has mapped the motions of structures of the nearby universe in greater detail than ever before. The maps are presented as a video, which provides a dynamic three-dimensional representation of the universe through the use of rotation, panning, and zooming. The video was announced last week at the conference "Cosmic Flows: Observations and Simulations" in Marseille, France, that honored the career and 70th birthday of Tully.
The Cosmic Flows project has mapped visible and dark matter densities around our Milky Way galaxy up to a distance of 300 million light-years.
The team includes Helene Courtois, associate professor at the University of Lyon, France, and associate researcher at the Institute for Astronomy (IfA), University of Hawaii (UH) at Manoa, USA; Daniel Pomarede, Institute of Research on Fundamental Laws of the Universe, CEA/Saclay, France; Brent Tully, IfA, UH Manoa; and Yehuda Hoffman, Racah Institute of Physics, University of Jerusalem, Israel.
The large-scale structure of the universe is a complex web of clusters, filaments, and voids. Large voids—relatively empty spaces—are bounded by filaments that form superclusters of galaxies, the largest structures in the universe. Our Milky Way galaxy lies in a supercluster of 100,000 galaxies.

I have viewed a lot of photographs and animations...the Hubble Deep field and the Scale of the Universe come particularly to mind...that present the immensity of our universe and the relative insignificance of our tiny speck of dirt orbiting a little bit of gas in a fair to middling bunch of similar systems.
The travelogue presented by the video of this data was an astounding experience. Being able to take various perspectives from the large scale structure of the galaxies in our neighborhood made the scale a far more real experience. Adding in the flows made the experience even more visceral.
What a great trip for a Friday morning!
The video should be shown and explained in every science classroom.
Thanks for the post, n2doc. 
thinking of Asimov's "Currents of Space" when I say the OP title
