# Are there other “fun” packages like the “coffee stains” package?

I'm trying to convert some friends to LaTeX and have come up against a (to me) unexpected objection: there are too few packages that support "fun" (really), to which I responded:

I know there are examples of clever and creative (and a bit silly) output coaxed out of otherwise quite sertious packages like TikZ, but I also wonder: Are there other packages, like Hanno Rein's coffee package, that demonstrate LaTeX's lighter side?

The nicest thing about LaTeX is that you don't have to see the actual Comic Sans text until you compile. – percusse Aug 18 '12 at 20:22
Does games count as fun? There are several packages for typesetting games such as chess and othello, as well as cross words. See the TeX catalogue: texcatalogue.sarovar.org/bytopic.html#games Edit: Also, bbcard for bullshit bingo and baseball cards. – Torbjørn T. Aug 18 '12 at 20:42
The coffee package is actually perfect for marking draft documents (OK, it is a little too manual and uses too much colored ink). I'd love if there were more options for that use case. – Benjamin Bannier Dec 18 '13 at 9:48

What about Peter Wilson's sudokubundle? You can print, create and SOLVE! sudokus.

Not a package, but could be packaged pretty easily: beamerduck!

The following presentation will show a progress by having a duck walk from left side of the screen to the right side, saying annoying things every once a while. You can of course replace the duck picture by any other animal (I am thinking about a man carrying a sack on his back. On specific slides, the ones I plan to spend more time on, I want to have him drop the sack to the ground and rest).

\documentclass{beamer}
\usepackage{tikz}
\usepackage{lipsum}

% Duck stuff

\usetikzlibrary{shapes.callouts, calc}

% Parameters: file, number of pages, width
\newcommand\DuckSetup[3]{%
\foreach \n in {1,...,#2}{
\pgfdeclareimage[width=#3,page=\n]{duck\n}{#1}}
\def\ducknumberofpages{#2}}

\DuckSetup{duck}{2}{1cm} % "duck" is a pdf file with 2 pages that will
% alternate as they move from slide to slide.

\newcommand\duck{%
\tikz[remember picture]{\node (duck) {%
\pgfmathparse{int(mod(\thepage-1,\ducknumberofpages)+1)}%
\pgfuseimage{duck\pgfmathresult}};}
}

\setbeamertemplate{footline}
{%
\pgfmathparse{(\thepage-1)*\paperwidth/\insertdocumentendpage}%
\hspace{\pgfmathresult pt}%
\duck
}

\newcommand<>{\ducksez}[1]{%
\uncover#2{\tikz[remember picture,overlay]{\node[ellipse callout, draw, fill=white, overlay,
callout absolute pointer={($(duck.north east) + (1,0)$)}] at ($(duck.north east) + (3,1)$) {#1};}}}

\newcommand<>{\ducksezrev}[1]{%
\uncover#2{\tikz[remember picture,overlay]{\node[ellipse callout, draw, fill=white, overlay,
callout absolute pointer={(duck.north west)}] at ($(duck.north west) + (-3,1)$) {#1};}}}
% End of duck stuff

No, the duck is the best appropriate to TeX.SX, read carefully the comments below the question above! ;-) – Speravir Mar 8 '13 at 4:05
OMG TEH DUCKS! ♥ – Paulo Cereda Mar 8 '13 at 11:38
This is pure genius. – Alfredo Hernández Feb 17 '14 at 22:41

Hope this counts. Cow font anyone :-)? It's part of TL Contrib.

So now, not only that you can make your documents coffe-stained, you can as well pretend you were pretty bored during your manipulation with the document, and you drew few cows on the paper margins... – yo' Aug 24 '12 at 11:11
My son loves cows, this is totally awesome! For all others which want to use it with LaTeX, you may find this: newsgroups.derkeiler.com/Archive/Comp/comp.text.tex/2009-06/… helpful. – math Oct 4 '12 at 9:03
+1 for "cows in math mode"! made my day :D – fifaltra Dec 29 '13 at 19:50

I like the chickenize package, which can do a lot of useless things, among others it can print in rainbowcolors. See yourself, works only with Lua(La)TeX.

-
The text looks mangled. Is this the final result of using this package? – Exeleration-G Oct 15 '13 at 8:02
@Exeleration-G No, as far as I remember that occured while makeing the jpg, which is displayed here. – Keks Dose Oct 15 '13 at 9:25

Well, there's always the package skull, which makes available a skull symbol for you to use in math mode. Fun, and of course extremely useful!

-
+1 for the 'usefulness' :) – Count Zero Mar 29 '13 at 21:57

I like the Tower of Hanoi, classical algorithm problem, illustrated and computed, via LaTex.

Tower of Hanoi in LaTex

You can also have the Simpsons family Demo here

You know what would be cool? A package for torn paper!

-
Still not a package but almost: Torn paper I and Torn paper II – Ignasi Mar 8 '13 at 9:10

You can have fun drawing Feynman diagrams with the feyn package... or is that just me?

-
I think that this is more fun-ctional than fun. I think the aim here is "frivolous and playful". – Niel de Beaudrap Aug 18 '12 at 21:12
Can it not be both fun and functional? I also realised that my answer was, perhaps, not exactly what the OP was looking for, but I thought it was a useful addition (and so did someone else). – User 17670 Aug 18 '12 at 21:45
My rule of thumb is this: of the number of documents it's used for, how many are using it to accomplish anything more than decoration or nonsense? I would imagine, at least, that the functional:fun ratio of feyn is quite high. – Niel de Beaudrap Aug 18 '12 at 22:27

run texdoc pst-fun, it shows some funny macros

Im using latex for 3 years now an no one told me about the texdoc command o.O thanks – sherif Sep 12 '14 at 9:35

With a lack of confidence, I present my own. However, it has not been bundled into a package. :-D

One of my students has taught himself TeX programming by developing:

In my opinion this is the most strange thing one can possibly do just for fun!

(But I am biased, of course :-)

Let's say we want to program our document in C on top of TeX. Then there would be the need to interpret the C semantics. Basically we would have to write a compiler for C in TeX. Not a very promising future, if you start this. But, we can use a normal C compiler to compile the C code to some simple platform. Like AVRs Atmega. Since I have other things to do than writing an AVR Emulator in TeX, here it is!

Actually, I even considered using this (!). In one of my lectures, I present lots of small AVR programs on beamer slides together with their "output" on a specific device with some LEDs and a 7 seg display. I already have been using LaTeX macros to typeset the status of the LED array and the 7 seg display, so the interpreter could, given the binary code, automatically derive the parameters for these macros. A special listings environment could automatically invoke the C-compiler (via \write18) to generate the respective binary code. The result would be truly "self-contained" slides: Whenever I change the given example code, the typesetting of the "output" would automatically be updated.

However, other deadlines were approaching, so in the end I dropped the idea.

I did not try it, but it sounds awesome. – Andy Apr 8 '15 at 15:23

Well, as you can see in some of the other answers, there are a lot of font packages out there with what some may call a questionable amount of uses.

A lot of the fonts mentioned in the other answer, and some other "silly" fonts are grouped under the The font-novelty topic on CTAN.

Not all fonts that can be considered "just for fun" or "silly" are listed under font-novelty, though. Here is some "fun" stuff outside of font-novelty :

• The font-invented topic on CTAN lists fonts for fictional/invented languages, it includes packages for Klingon and several of J.R.R. Tolkien's Middle-Earth alphabets. There are also typesetting support packages for some of these languages listed under the CTAN's lang-invented topic.

P.S. I intended to post more links while typing this up, but SX won't let me post more than two links because I'm still a greenhorn over here. I'm planning to update this answer once I rack up some more reputation :)

While the language/usage might be fictional but they are proper fonts. So it doesn't really classify as fun I would say. Besides they are also in TeX-SX logo so known to people here pretty much. – percusse Mar 17 '15 at 14:26
