In my town there will be next weekend an exhibition with 7000 donkey images. It is related to a sculpture group with 7 donkeys called "donkey's way" which will be installed in the summer.

I would like to add one (or perhaps more) TeX-donkey images.

If you would like to participate and create one: you are completely free to choose the look and implementation. Additional ducks and lions are allowed.

I will choose the one I like best (I will take votes into account), print it out, add your name(s) and put it in one of the boxes which collects the images.

If you need inspiration: There is a Facebook group "7000Esel", which shows some already existing images. The official logo of the project looks like this:

enter image description here

I will also add a bounty to this question as soon as possible -- which means after Paulo's bounty has be awarded. (But I regret that I can't split the bounty among all this beautiful donkeys (and ducks in disguise)).

Update

I made prints from all the answers (if the authors would get a pdf: drop me a mail) and brought them to the exhibition. I will try to make fotos on sunday and post them.

Update

I went to the exhibition. There were thousands of donkey images side-by-side in a number of corridors.

Among these various tex donkeys (I couldn't put all in the boxes as there was a time limit).

There was also an image of another disguised duck:

I'm very satisfied and thank everyone for their contributions ;-)

  • Must this be TeX (Tikz) or is a svg or pdf also allowed? – MaestroGlanz May 30 '16 at 12:30

    @MaestroGlanz: As I'm asking this on tex.sx and I'm asking for a TeX-donkey, there should be some TeX in it, but external resources are allowed. As I wrote you are quite free regarding the implementation. You can e.g. draw a donkey on paper and scan it. Only don't violate rights of other people by using some random image from the net. I don't want to get sued ;-) – Ulrike Fischer May 30 '16 at 12:40

    @EthanBolker Something like this? I only just saw your comment having posted ;). Though I went with Don{Knuth} rather than DonK(nuth). Not sure where you'd find a picture of an ey. – cfr May 31 '16 at 3:21

    @PauloCereda: But I wanted to add a bounty ;-(. What happens if I add a bounty too? Can we split them? (The justification for the bounty is naturally wrong. I got some very neat donkeys -- which were very well received. – Ulrike Fischer Jun 1 '16 at 14:21

    ooh I saw another duck disguised as donkey. :) – Paulo Cereda Jun 6 '16 at 17:23

Here are three varieties of an alternative rendering of a donkey based on an openclipart image by Timothy King. But note that Inkscape exported useless code so the correspondence with the original is poor in all three cases.

Variant 1 (Original)

don-key 1

Variant 2 (Shiny)

don-key 2

Variant 3 (Power of Knuth)

don-key 3

Variant 3 (Power of Knuth)

The code for the third variant causes the answer to exceed the length limit. While one donkey answer may be considered a misfortune and two explained by mere carelessness, a third would surely constitute deliberate trespass beyond the bounds of propriety. Hence, here is the source code in question.

In response to a suggestion by the OP in chat, I am pleased to announce the availability of a provisional logo for the TeX Society for the Protection of Donkeys (TSPD).

TSPD

The donkey itself is an adaptation of an openclipart.org donkey by frankes. The original SVG was opened in Inkscape and exported to TikZ code. This code was then partially cleaned and modified. A simple key-value interface was added to configure the donkey's colouring.

The donkey code became asyn.tex. This was compiled to PDF using pdfLaTeX.

donkey

asyn.pdf was then used to create the logo using TikZ code based on that I used to create the TSPCD circular logo posted in chat a couple of days ago.

  \path [decorate, decoration={text effects along path, text={\TeXT\TeXe\TeXX \textbullet{} SOCIETY \textbullet{} FOR \textbullet{} THE \textbullet{} PROTECTION \textbullet{} OF \textbullet{} DONKEYS \textbullet{}\ }, text effects/.cd, text along path, fit text to path, characters={font=\LARGE, text=Silver}}] (90:38mm) arc (90:-270:38mm);
  \node {\includegraphics[height=50mm] {asyn}};
\end{tikzpicture}
\end{document}

The PDF compiled by pdfLaTeX was finally converted to PNG using ImageMagick's convert utility.

convert -density 300 <filename>.pdf -quality 100 tspd.png

Since TSPCD and TSPD have very similar acronyms, it is essential to bear in mind that

duck \neq donkey

or, in code,

$x \neq y \forall x \in \{\text{donkeys}\}, y \in \{\text{ducks}\}$

TSPCD; duck; donkey; TSPD

Caveat emptor ...

Appendix

The code for the duck is the duckastic work of the site's resident duck, Paulo Cereda, posted in this answer.

The system will not allow me to post the source asyn.tex which contains the code for the donkey here, even in a dedicated answer and even if I remove all permissible spaces and do some further compacting codewise. But I have found a solution allowing me to post the donkey source code used to create asyn.pdf.

Code for inequality:

\documentclass[tikz,border=10pt,multi]{standalone}
\usetikzlibrary{positioning}
\begin{document}
\begin{tikzpicture}
  \node (hwyaden)  {\includegraphics{duck}};
  \node (n) [right=of hwyaden, font=\Huge, scale=10] {$\neq$};
  \node [right=of n] {\includegraphics{asyn}};

This is my randomized TeX donkey contribution, made with Tikz. The idea is the emerging of the letters of "Esel" from the central TeX following an Archimedes spiral.

randomized TeX donkey

The letters are chosen randomly and have random size and rotation. An advantage of this approach is that the silhouette of the donkey has not to be very perfect. I like this kind of design as a logo because it is immediately recognisable, but every time that it is compiled (with at least 1 min difference), the output is slightly different because it has a random component.

I posted the following artworks in the chatroom, and I was kindly asked to posted them here as well. I am also marking this answer as community wiki since there is no need to harvest these juicy reputation points. :)

The first artwork is an attempt of reproducing the official project logo as a vector image. I drew it by hand and made some conversions in order to obtain the corresponding .tex code, available in this GitHub gist due to code length limitations in our site. The result is as follows:

Quack

The second artwork was made as a recurring joke in the chatroom, as we are fond of ducks. What if a duck wants to win the contest and goes into the competition disguised as a donkey? Then we came up with the following drawing, with the corresponding .tex code available in this GitHub gist for the very same reasons stated above:

Quack

Although the disguise is almost perfect, some smart bloke might argue there is no yellow donkey available in nature. Then we are now inclined to provide a improved version of the duck's disguise, as seen in the following image (.tex code provided in this GitHub gist):

Quack

The final improvement would be making the duck wear green contact lens, so the donkey disguise would be technically perfect. Maybe in the upcoming future. :)
