# Placing text at random positions on the screen in beamer

I am creating a presentation and for the Q&A session slide, I want to show question marks (?) in various colors and sizes in random locations on the screen.

Is this possible in beamer?

Yes, with beamer and tikz it is:

\documentclass[xcolor=rgb]{beamer}
\usepackage{tikz}

\begin{document}

\begin{frame}{Questions}
\begin{tikzpicture}
\foreach \i in {1,...,30} {
\pgfmathparse{rnd}
\definecolor{MyColor}{hsb}{\pgfmathresult,1,1}
\pgfmathparse{3.0*rnd+1.0}
\node[text=MyColor] at (8*rnd,6*rnd) {\scalebox{\pgfmathresult}{?}};
};
\end{tikzpicture}
\end{frame}

\end{document}


Here's the result:
