(Improved answer thanks to Bruno's help on his code) I've implemented some of the things I mentioned in my earlier answer, but I felt this was different enough to get a separate answer. Once again, tex.sx provided me with a couple of things I needed for this. Bruno Le Floch wrote some code that rotates arguments at a random angle and helped shortening it ...

This has been a topic for a few questions on this site and you can find many examples of such human-like typesetting, the most famous being the great How do I make my document look like it was written by a Cthulhu-worshipping madman? and also slightly related ones Simulating hand-drawn lines TikZ two-blocks matrix that I can remember (because I've ...

The following image illustrates the blowup of a plane at a point--an important construction in algebraic geometry (compare the cover of this book). The image was produced using Asymptote. (Note: the code and the image have both been refined since they were first posted.) The vector image may be viewed by following this link. settings.outformat="pdf"; ...

Electric field due to 3 charges.

One that I'm most proud of is a three-dimensional illustration of a signpost with various loads applied, shown here. I used the TikZ package. Commercial fonts have been removed in the code I've posted below. Looking back at the code, I probably could have written it a bit more efficiently (styles for face shading, more relative positioning, etc.), but c'est ...

One of my favorites; this one's not so involved but I enjoy the simplicity of the code and the quality of the result. It uses pgfplots to display streamline data for vortex shedding from a square block at Re=100. The streamline data were computed by a Fortran code I wrote to model the flow. The code: \documentclass{standalone} \usepackage{pgfplots} % ...

Plan B as per tohecz: I'm a security engineer at Facebook and this is my fault. Properties of water and steam (IAPWS-SF95 formulation), enthalpy-entropy diagram, actually used by our students (and colleagues, from time to time). Compiled with lualatex for memory reasons. I'll not post the code here, as it is quite a lot and wouldn't work on other computers ...

I made a humble attempt of a cute document with memoir and some Inkscape graphics. :) Please bear with me, after all, cuteness is in the eye of the beholder. :) Spoiler alert: ! Don't laugh at my duck, please. Jake and I were talking in the TeX and friends chatroom a few months ago about funny chapter styles for memoir. For the fun of it, we made a ...

Going straight to the source, the H.P. Lovecraft Society offers a number of fonts (some free, some for sale), including Lovecraft Cursive (unfortunately not part of the free set). The whole set of 50 fonts is available for $35.00 and contains more than 80 beautifully rendered digital props. A quick Google search for "free handwriting fonts" finds this site:...

Inspired by @Paul Gessler, the following is a statics problem from a class I taught. The problem was to find the maximum weight the crane could carry as a function of distance before it would tip over (the supports at D and E aren't bolted to the ground). It uses the drawing and plotting capabilities of TiKZ to draw the crane and the solution. Looking back, ...

Here is my take: Update: More "bling bling", more compilation time...

My humble attempt (thanks to xelatex): My code to question #29402 on TeX.SX I'm sorry, friends. TeX.SX seems to forbid answers with more than 30,000 characters.
