Welcome to my home page! Here you'll find a list of some of the cool projects I've been working on.
For starters, check out my masterpiece, Scott Pakin's Automatic Complaint-Letter Generator.

Word-Filtering Program helps you solve
guess the mystery
You can download the source code for dot2ubi (.tar.gz format, 6536 bytes), a small program that renders Graphviz DOT files as interactive 3‑D models using UbiGraph. Although brief, dot2ubi documentation (PDF) is also available.
Prefer 2‑D artwork? Check out my Context Free Art gallery. (Click on each thumbnail for a larger view.) Context Free is a piece of software that lets one create artwork by combining simple geometric shapes in a variety of complex configurations.
I wrote a handy little Gimp script entitled center-selection, which crops an image so as to center the current selection within the image's boundaries. I also created a utility called Netpbm2Gimp that facilitates programming Gimp filters by reimplementing the easy-to-use Netpbm API in terms of Gimp library calls. If you're not a programmer, check out gimp-netpbm2gimp-plugins, a collection of hundreds of Gimp filters automatically converted from Netpbm utilities using Netpbm2Gimp.
Speaking of the Netpbm utilities, I authored a few of them myself: avstopam, pampaintspill, pamrecolor, pamsistoaglyph, pamstereogram, pamtoavs, pamtodjvurle, pamtooctaveimg, and pbmtodjvurle. I also helped improve other people's Netpbm utilities by submitting bug reports for every bug I encountered.
If you run Ubuntu Linux or a derivative, you may be interested in two of my Personal Package Archives (PPAs)—collections of software conveniently packaged for installation on an Ubuntu system (PPA usage instructions):
Did you know that PDF files can contain interactive 3‑D models? An example PDF file with embedded 3‑D that I produced demonstrates this feature. (Alas, I believe it requires Adobe Acrobat or Adobe Reader; otherwise the document is non-interactive.) I created that PDF file using exclusively free, open-source tools: Blender for the 3‑D modeling, my Asymptote Export script to export Blender models to Asymptote source code, Asymptote to output the model in PRC format, and LaTeX (specifically, pdfLaTeX) to include the graphic in a PDF file and typeset some text above it.
Scott Pakin works as a computer scientist in New Mexico, USA. That information makes this paragraph a valid hCard, which enables Google to associate a picture with my name in search results. Hooray!
