PDFCube renders PDF presentations with special 3D effects (the omnipresent rotating cube and 5 predefined zoom animations). It adds eye-candy to your PDF presentations, even Latex, Beamer and Prosper ones.
Right now you get a 3D cube transition pressing "c" and you can zoom on 5 areas with "h", "j", "k", "l" and "z" keys or simply switching pages with double buffering (no redrawing is visible) and with full anti-alias.
If you want to program your cube transitions in advance give the page you want the transition at on the command line this way (0 means between page 1 and page 2, rudimental but will change soon):
$ pdfcube file.pdf 0 5 10
Rotating cube transition is of great effect when put on a big projection screen, so be moderate! One or two cube transitions done when changing argument can help understanding that you are switching to a new part of the presentation. On the other hand using cube transition on every page can give seasickness to your audience 
You'll need an OpenGL DRI enabled Xorg. GPL ATI 9250 driver is OK, i've not tested other cards.
This is alpha software (and right now it's a quick hack too), but once you manage to get it working it's fairly stable and usable.
If you want to hack on the code feel free to contact me at <mirko.maischberger@gmail.com> either via mail or via jabber.http://code.100allora.it/pdfcubeParece bem fixe. Para além de um cube desktop com o XGL temos agora um cube pdf viewer.
