3D pdf and interactive 3D data in scientific publishing

Prof. Goodman at the Harvard astronomy department published her latest
Nature paper with 3D figure that you can rotate and manipulate inside
the pdf.

The 3D pdf can be downloaded here though the
link on the right "PDF 3D version."

A movie demonstrating the features of the 3D PDF can be found on
Goodman's webpage.

I downloaded the 3D pdf and it really does work. (I used Acrobat Reader
8.1)

This seems like an interesting way to visualize complicated data.
