Apparition effect without the beamer package

Question

I want to implement a presentation template in LaTeX that look very like the one here.

Until here, I did just fine using the article class with geometry, tikz and some custom commands. However a problem arose: the article class does not implement apparition effects!

Beamer allows to do such things (with commands like \pause, \only, etc.) but the code that manage it (beamerbaseoverlay.sty if I am not mistaken) doesn't look like being included in something other than beamer-class documents...

Does anyone know a package that would add apparition effects to LaTeX document. Or a way to add beamer's code to mine?

Answer 1

The texpower package allows for pauses and transitions of many sorts, without beamer. So you can use, for example, the article class, and set the page size and margins to anything you like with geometry, and produce documents that look nothing like beamer, and perhaps like nothing on earth. Here’s a silly example:

\documentclass[12pt,svgnames]{article}
\usepackage{eso-pic,fontspec,microtype}
\usepackage[display]{texpower}
\setmainfont{Antique Olive FS}[
  Color=DarkGreen]
\linespread{1.103}
\setlength{\parindent}{0pt}
\usepackage[centering,papersize={288pt,384pt},hmargin=1.5em,tmargin=55ex,bmargin=1.5em]{geometry}
\AddToShipoutPictureBG{%
  \AtPageLowerLeft{%
\put(0,0){\makebox(0,0)[lb]{\includegraphics[width=\paperwidth]{nip}}}}}

\pagestyle{empty}
\begin{document}
\Large\bfseries
If you gaze long into the catnip,\pause
the catnip also gazes into you.\pause
\begin{flushright}
  –Henri, le Chat Noir
\end{flushright}
\end{document}

But texpower is capable of much more than this; compile fancyexample.tex from the documentation for something very impressive.
