I also tried high Density Diffusion - loved the slower movement and that made me think - only if there was a way to export that to a something like a moving wallpaper that I could set to my Ubuntu desktop.
Also, just setting Density Diffusion to 1 and leaving makes the movement slow enough to be able to screenshot nice wallpapers.
I do. Coming from Win 3.1 and due to restrictions on internet connectivity in our office then, at first I had no idea how to use it and thought it was some advanced feature.
Density diffusion: just a hair under 1(visually)
velocity diffusion: 0.99
pressure: 0.93
vorticity: 5
