PovRay Gallery

PovRay is an open-source raytracer with its own scripting language for describing scenes. It render beautiful images and animations. It is a dinosaur, but also, there is no modern software quite like it. Some example images here: Gallery

Dylan's Yo-yo

Grad students at UC Santa Barbara while I was there were allowed to take any class, even undergraduate classes not particularly related to their field of study. I took advantage of this one time. I chose an Animation survey class, and it changed my life. One of the homework assignments was to create a "cycle", a short animated video clip that loops. This one was mine; it's called Dylan's Yo-yo: Dylan's Yo-yo on YouTube

Multiplication Tables for Symmetric and Alternating Groups

During a long layover I wrote a python script to generate svgs of multiplication tables for permutation groups. Here is the result: Multiplication Tables for Symmetric and Alternating Groups

Lightbulb

In around 2007, I spent months using PovRay (and other tools, including some software I developed) to make this 3D model of a lightbulb, and then my computer spent days rendering it. Lightbulb on YouTube

Geometric Median Toy

My dad posed an interesting math problem to me recently, which it turns out has a name "Geometric Median". The geometric median of a set of points S is the point P which minimizes the sum of the distances from P each of the points in S. In my dad's version, the points in S are the places of residence of the members of a band, and the point P is the ideal location at which to hold rehearsal to minimze total travel cost. I made a piece of software to investigate the geometric median interactively. Geometric Median Toy
