The hierarchical domains in the velocity field shown in this paper made the cover of Science Magazine last February (2012)!

The cover shows a small region from a poster that was awarded the first place in the National Science Foundation International Visualization Challenge in the poster category. The full description can be seen in the February issue of Science Magazine. I made the poster together with Julieta Aguilera and Mark SubbaRao from the Adler Planetarium. The poster can be seen interactively below:
