and its first frame of animation. Data from Brent Tully of the University of Hawaii. We plot actual observed galaxies within this radius, with Tully's reconstructed 3-D positions. The "clouds" are isosurfaces of smoothed number density of galaxies. Thus the clouds indicate where the galaxies cluster. It's clear that their distribution is full of clumps and long filaments, surrounded by lots of nearly-empty space. Rendered with RenderMan.

Data from Glen Wheless and Cathy Lascara, Center for Coastal Physical Oceanography, Old Dominion University.
Of these data, Glen writes:
The isosurface shows the position of a particular value of a tracer which
simulates the position of a patch of larval fish. The color represents
the salinity at that location, red being very saline and yellow being more
fresh. The simulation is a 15 day run, tides are semi-diurnal, in other
words, 2 highs, 2 lows per day. Winds originally blow from SW to NE then
reverse, simulating a low passage or northeaster. You can see how the wind
blows the 'fish' away then back to the mouth of the bay where the tides
then act to bring some of the fish into the Bay, possibly serving as a
mechanism for retention.

Data from Crystal Shaw and Bob Wilhelmson.
The orange contour lines are for vertical wind velocity, contoured at 3 m/sec. Vertical wind velocity is also mapped as the color onto the rain water isosurface contoured at 6 grams per grams of air. It also looks like the rainbow color map goes from purple (downdraft) to red (updraft).

This version shows tracers color-coded by upward-component of velocity: orange for rising (presumably warm) air.
