Some of the most stunning flow renderings I have seen come are here:

http://skysrv.pha.jhu.edu/~miguel/videos.html

In particular, I would love to know how to re-create "Interactive visualization of the Cosmic Web" video (even if without the interactive part). Any ideas? If I remember correctly, that video was made with LIC that Mike wrote about in his vector flow plot.

And apologies to Petros for not having a solution and posting (hopefully) a teaser.

Cheers,
Manodeep
