Hi, The latex-beamer-users list <latex-beamer-users at lists.sourceforge.net> points to a new version 2.0 of the TikZ/pgf, in particular, Kjell Magne Fauske points to an overview at his site: <http://www.fauskes.net/pgftikzexamples/pgf-version-2/> Perhaps TeXLive-2007-Dev and gwteX would be updated too.
