\title{Graphics in \LaTeX}
\date{}

\maketitle

Here is an image of this very document:
\begin{center}
\includegraphics[scale = 0.5]{self.png}
\end{center}

\noindent  % \noindent tells LaTeX not to indent this paragraph if it normally would.
Here is an equation in a Flatland textbook after you have gone through the reversing region: 
\begin{center}
\reflectbox{Euler's identity tell us that $e^{i\pi} + 1 = 0$}
\end{center}

\noindent
You can also rotate text \rotatebox{30}{like this.} \rotatebox{180}{Or even like this!}

\noindent
You can also \scalebox{1.5}{scale} things, though there is usually a better way to get the same effect.

There are \color{red}color\normalcolor \ \color[rgb]{0.1, 0.5, 0.2}extensions\normalcolor \ in the {\tt color} package, as well.
