Move TikZ cloud in a better position using beamer

Question

I am trying to manipulate the exact position of a TikZ cloud but I am not sure if I'm doing any effort at all.

As you see in the aforementioned picture the space between items is not beautiful. So I tried to add it outside the itemize enviroment. It seems, though that it's not following my commands. The code I am using is

\documentclass[slidestop,compress,mathserif,12pt,xcolor=dvipsnames]{beamer}
\graphicspath{{images/}}
\definecolor{LHCblue}{RGB}{4, 114, 255}
\usecolortheme[named=LHCblue]{structure}
\usepackage[bars]{beamerthemetree} % Beamer theme v 2.2
\usepackage{kerkis}
\usepackage{multimedia}
\usepackage{subfigure}
\mode<presentation>
%frame
\newcommand*\oldmacro{}%
\let\oldmacro\insertshorttitle%
\renewcommand*\insertshorttitle{%
     \oldmacro\hfill%
  \insertframenumber\,}%/\,\inserttotalframenumber
\setbeamertemplate{footline}[frame number]
%~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\setbeamercovered{higly dynamic}
\usetheme[watermark=ntua-logo.jpg]{Ilmenau} % Beamer theme v 3.0
\useoutertheme[subsection=true]{smoothbars}%Beamer Outer Theme-circles on top

\useinnertheme{circles} %rectangle bullet points instead of circle ones
\usepackage{beamerthemebars}
\setbeamercolor{navigation symbols dimmed}{fg=red!80!black}
\setbeamercolor{navigation symbols}{fg=red!80!black}

at(current page.north east){Thank you Rui!};
\end{tikzpicture}
\end{frame}

\end{document}

Any ideas for this?

Aw, percusse was faster. I basically did the same, but turned it into a macro with the parameters [angle]{content}:

Code

\documentclass{beamer}
\usetheme{Darmstadt}
\usepackage{tikz}
\usetikzlibrary{shapes}

\newcommand{\Cloud}[2][180]% [angle], content
{   \begin{tikzpicture}[overlay]
        \node[align=center, draw, shading=ball, text=white, cloud callout, cloud puffs=17, cloud puff arc=140, callout pointer segments=3, anchor=pointer, callout relative pointer={(#1:2 cm )}, aspect=4,scale=0.5] at (0.2ex,0.5ex) {#2};
\end{tikzpicture}
}

\begin{document}

\begin{frame}[t]
    \begin{itemize}
        \item XY Resistive MM\Cloud{Thank you Rui}
    \item Manufactured by Rui de Oliveira\Cloud[160]{Thanks again}
    \item bla bla bla\Cloud[120]{Thanks yet another time}
    \end{itemize}
\end{frame}

\end{document}

Result

Oh I think yours is much more structured, I've deleted mine. Can you include the obsolete options warning in your answer? – percusse Sep 27 '12 at 12:46
Actually, as I simplified the given MWE a lot, no such warnings appear for me. – Tom Bombadil Sep 27 '12 at 13:01
Thank you guys very much! I really liked the newcommand. It is really fancy! Thank you both soooo much!!! – Thanos Sep 27 '12 at 13:19
@percusse: did it in my answer. – Claudio Fiandrino Sep 27 '12 at 16:21

Here is another approach: at first the point where the cloud should start is marked and then the could is positioned starting from that position. The command \mycallout is overlay-aware therefore allows you some customization.

Notice that you can position a cloud regardless having marked a point, but doing it allows the pointer to be vertically aligned with respect the sentence (the last cloud is not).

Percusse suggested to comment the warning deriving from your code:

the option slidetop:

Class beamer Warning: slidestop'' is obsolete. Uset'' instead on input lin e 343.

the option mathserif:

Class beamer Warning: mathserif'' is obsolete. Use font themeserif'' with option ``onlymath'' on input line 343.

You can avoid them by means of substituting the first two lines in your code:

\documentclass[t,compress,12pt,xcolor=dvipsnames,]{beamer}
\usefonttheme[onlymath]{serif}

Notice that also the snakes library is obsolete: you can use decorations although in the current example is not needed.

The equivalent xparse-free solution:

\documentclass[t,compress,12pt,xcolor=dvipsnames,]{beamer}
\usefonttheme[onlymath]{serif}
\usepackage{lmodern}
\graphicspath{{images/}}

It seems that writing thesis trim down the programming quickness :D — Claudio Fiandrino, Sep 27 '12 at 12:32
Thank you very much for your answer! Your comment, is striking directly on the spot :) But OK, I admit it: I am not a software guy...!!! The thing about your answer is that it isn't working on my system. Somehow NewDocumentCommand seems to be very nasty for my system... — Thanos, Sep 27 '12 at 13:17
My comment was related to the fact that it took to me too much time to write the answer. For what concern NewDocumentCommand: do you have problems with the xparse package? I've use it mainly to have the possibility of declaring as delimeters <> for the overlay specifications. — Claudio Fiandrino, Sep 27 '12 at 15:59
