+Summary: Some of the tools I use for making and giving presentations.

+
+# Introduction
+
+Over the past year, I have to give quite a few presentations in different
+contexts: internal to the company, for open-source conferences, for business
+conferences…
+
+I use this opportunity to refine a bit my presentation tools, and I just
+summarize them here for curious people.
+
+This page may be updated, for instance if I start using [typst] for slide making.
+If you have subscribed to this blog’s [RSS feed], you will be notified of future
+updates.
+
+# Making slides
+
+For slide making, I prefer using tools that separate the content from the actual
+design. I’m thus not using fancy WYSIWYG tools for that. If you are not
+interested in that, you can already skip to the [presenting slides] section.
+
+## LaTeX beamer
+
+As explained in the [typst article], I’m mostly using [LaTeX] to produce/typeset
+documents, and presentations are not an exception. For this purpose I’m using
+[beamer].
+
+For this purpose, my [vim setup for LaTeX] proved to be pretty useful, even
+though the backward search is not very accurate with beamer slides.
+
+The main advantage, besides my familiarity with [LaTeX], lays in the [overlay]
+system in beamer, that is quite powerful and provides a very precise way to
+display elements, especially with [TikZ] to design animated graphics.
+
+For instance in the example below, I can show the top part of the graph
+initially, then the bottom, and change the name of the last node for the second
+slide. That can be easily adjusted to have more steps in the process.
+
+```latex
+…
+\usetikzlibrary{positioning}
+…
+\begin{tikzpicture}
+  \tikzstyle{node} = [draw, rectangle, fill=blue!40, minimum height=2em]
+  \tikzstyle{arrow} = [->, >=stealth, very thick]
+  \node[node] (start) {Data};
+  \node[node, right=1cm of start] (a1) {Enc($\cdot$)};
+  \node<2->[node, below=5mm of a1] (a2) {Sig($\cdot$)};
+  \node<1>[node, right=1cm of a1] (stop) {Encrypted Data};
+  \node<2->[node, right=1cm of a1] (stop) {Encrypted and Signed Data};
+
+  \draw[arrow] (start) -- (a1);
+  \draw<2->[arrow] (start) -- (a2);
+  \draw[arrow] (a1) -- (stop);
+  \draw<2->[arrow] (a2) -- (stop);
+\end{tikzpicture}
+```
+
+Resulting in:
+
+![The last image from the above code](../examples/tikz-graph.svg "The last image from the above code"){width=66%}
+
+Moreover, you have access to the whole latex ecosystem, especially those for neat illustrations such as [tikzpingus]
