combine tikz and beamer

[Arne Röhrs]

Hello,

i have a problem to combine tikz and beamer.

A photo should be illustrated with some clouds. The positioning of the  
clouds works fine, but the clouds
should not appear at the same time. They should appear step by step.
It ist possible to create for every cloud a new frame, but that is not  
a good solution.
See the code below.

Knows someone a better solution?

Best regards

Arne

PS: Know someone how to change the color? I don't want this kind of  
orange. I want a darker orange. But how can I define the color?

\documentclass[12pt,%
%handout%
]{beamer}
\usepackage[T1]{fontenc}
\usepackage[applemac]{inputenc}
\usepackage{ngerman}
\usepackage{tikz}
\usetikzlibrary{arrows,snakes,shapes}
\usepackage{graphicx}
\usepackage[absolute,overlay]{textpos}
\usepackage{graphicx}
\usetheme{Singapore}

\setbeamercovered{transparent}
\setbeamertemplate{navigation symbols}[vertical]%{}
\usecolortheme[%
% named=red,
% named=blue,
% named=green,
        named=orange,
% named=gray,
% named=NavyBlue,
%  named=RoyalBlue,
%  named=MidnightBlue,
%  named=CadetBlue,
]{structure}

\begin{document}


\frame
{
\frametitle{Medien zum Einstieg}
\centering
\includegraphics[scale=.3]{wundenmann}
\begin{tikzpicture}[remember picture,overlay,
note/.style={cloud callout, cloud puffs=15, aspect=3, cloud puff

\end{tikzpicture}

\transboxout

}

Have you tried using Beamer overlays? Something like this maybe:
...
\node<1-> [xshift=1cm,yshift=5cm,note, callout relative pointer=
{(-1,-1)},fill=green!70!black] at (0,0) {Kommunikation};
\node<2-> [xshift=-3cm,yshift=5cm,note, callout relative pointer=
{(1,-1)},fill=blue!90!black] at (0,0) {Fachwissen};
\node<3-> [xshift=1cm,yshift=1cm,note, callout relative pointer=
{(-1,1)},fill=red!90!black] at (0,0) {Bewertung};
  \node<4-> [xshift=-3cm,yshift=1cm,note, callout relative pointer=
{(1,1)},fill=gray!90!black] at (0,0) {Bewertung};
...

Exactly my thought.  (You can use nearly all of Beamers' overlay facilities in
a tikzpicture.)

I prefer \node<+->, which makes it easier to reorder the bubbles.

HTH,
