I am interested in building a beamer slide with a background similar to the one displayed when TexStudio is started, I don't know where to start. any ideas how to accomplish this?

Basically, I want to have a color gradient background with small sized equations distributed all over the slide

Here is the image I am talking about

TexStudio Logo

I am donde with the color background part but I am having difficulties to create random math equations, I've tried with the \blindtext package but I only want random math equations, not text. This is a MWE

\documentclass{beamer}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage{tikz}
\definecolor{arsenic}{rgb}{0.23, 0.27, 0.29}
\definecolor{darkspringgreen}{rgb}{0.09, 0.45, 0.27}
\setbeamertemplate{background canvas}{%
\begin{tikzpicture}[remember picture,overlay]
\shade[top color=arsenic,bottom color=darkspringgreen]
  ([shift={(0cm,-0cm)}]current page.north west)
     rectangle
  ([shift={(-0cm,0cm)}]current page.south east);
\end{tikzpicture}%     
}
\setbeamertemplate{navigation symbols}{}
\usefonttheme[onlymath]{serif}
\begin{document}

\begin{frame}
\textcolor{white}{\blindmathpaper}
\end{frame}

\end{document}

    Licence permitting, \includegraphics seems the obvious way to go. – cfr Mar 11 '17 at 4:30
  • It is a nice idea but I dont wat to display the reflectors and te letters, I´ve edited the question to be more specific, I want to have a color gradient background with small sized equations distributed all over the slide – Paul Lara Mar 11 '17 at 4:44
  • Then I suggest adding some code showing what you've tried. A gradient background should be pretty straightforward. Just look at Beamer's documentation. – cfr Mar 11 '17 at 4:49
  • Or make something suitable in Inkscape and include the image, if you don't want to expend effort on the documentation. – cfr Mar 11 '17 at 4:50
  • I have edited my question once again with a MWE, now my question is just about the random math expressions. – Paul Lara Mar 11 '17 at 5:35

This is the best I can do:

\documentclass{beamer}
\usepackage[english]{babel}
\usepackage{blindtext}
\makeatletter
\newcommand{\moremathintolatex}{
    \blindtext@formula
    \blindtext@formula
    \blindtext@formula
    \blindtext@formula
    \blindtext@formula
    \blindtext@formula
    \relax%
}
\makeatother
\usepackage{tikz}
\definecolor{arsenic}{rgb}{0.23, 0.27, 0.29}
\definecolor{darkspringgreen}{rgb}{0.09, 0.45, 0.27}
\setbeamertemplate{background canvas}{%
    \begin{tikzpicture}[remember picture,overlay]
    \shade[top color=arsenic,bottom color=darkspringgreen]
    ([shift={(0cm,-0cm)}]current page.north west)
    rectangle
    ([shift={(-0cm,0cm)}]current page.south east);
    \end{tikzpicture}%     
}
\setbeamertemplate{navigation symbols}{}
\usefonttheme[onlymath]{serif}
\begin{document}

    \begin{frame}
        \textcolor{white}{\moremathintolatex}
    \end{frame}

\end{document}

As the final result is not too nice, consider this just a possible starting point. I've tried to introduce some randomness in CarLaTeX's solution.

First I've stolen blintext formula and converted it to a command. Second this command is used as text into a node which is randomly placed on background.

You can decide how many formulas to use, which formulas to use, and how to define their placement.

\documentclass{beamer}
\usepackage[english]{babel}
\usepackage{blindtext}
\makeatletter
\newcommand{\moremathintolatex}{
    \blindtext@formula
    \relax%
}
\makeatother

\newcommand{\myformula}[1][0]{%
\ifcase#1%
$\displaystyle\bar x = \frac{1}{n}\sum_{i=1}^{i=n} x_i = \frac{x_1 + x_2 + \dots{} + x_n}{n}$
\or 
$\displaystyle\int_0^\infty e^{-\alpha x^2} \mathrm{d}x =
\frac12\sqrt{\int_{-\infty}^\infty e^{-\alpha x^2}}
\mathrm{d}x\int_{-\infty}^\infty e^{-\alpha y^2}\mathrm{d}y =
\frac12\sqrt{\frac{\pi}{\alpha}}$
\or 
$\displaystyle\sum_{k=0}^\infty a_0q^k = \lim_{n\to\infty}\sum_{k=0}^n a_0q^k =
\lim_{n\to\infty} a_0\frac{1-q^{n+1}}{1-q} = \frac{a_0}{1-q}$
\or 
$\displaystyle x_{1,2}=\frac{-b \pm \sqrt{b^2-4ac}}{2a} = \frac{-p \pm \sqrt{p^2-4q}}{2}$
\or 
$\displaystyle\frac{\partial^2 \Phi}{\partial x^2} + \frac{\partial^2 \Phi}{\partial y^2} +
\frac{\partial^2 \Phi}{\partial z^2} =
\frac{1}{c^2}\frac{\partial^2\Phi}{\partial t^2}$
\or 
$\displaystyle\sqrt[n]{a} \cdot \sqrt[n]{b} = \sqrt[n]{ab}$
\or 
$\displaystyle\frac{\sqrt[n]{a}}{\sqrt[n]{b}} = \sqrt[n]{\frac{a}{b}}$
\or 
$\displaystyle a\sqrt[n]{b} = \sqrt[n]{a^n b}$
\fi%
