Flashback to January 2016!

teaching machines


Two days before the semester started, I had one of those first-day-of-teaching nightmares. Sure enough, my wardrobe malfunctioned. This dream was probably inspired by my real pair of pants that had lost a button. When I told my wife about the dream, she offered to fix the pants. I told her the button was on […]


There’s something magical about wooden crates. Here’s a little program that recreates that magic on a small scale by subtracting away some triangular prisms from each face of a cube: I printed the model in wood filament, and I can almost see a miniature dock worker sitting on it and eating his lunch: A miniature […]

Speed Coding in Madeup: D6 Edition

I have n ideas in my head of things I want to make in Madeup, and they are starting to fight with each other for my attention. I think it’s time to send some of them packing. Here’s one of them: a speed coding of the obligatory six-sided die.

I mentioned many things in the last status report and we’ve accomplished the following since then: Added a solid wireframe mode. […]

Since I’m teaching a couple of game development courses this semester, I offered some extra credit to students who attended. For proof of attendance, students had to submit a selfie, a receipt, a soiled napkin, or […]

Ask a Scientist Talk

This is the manuscript of a talk I gave at the Acoustic Cafe on April 20, 2016, as part of UWEC’s Ask a Scientist speaker series. Thanks, Paul Thomas, for the opportunity to share my work! Introduction Hi, I’m Chris. I teach machines. I also teach people to teach machines. I like both of these […]

Madeup Lock Core

I worked on creating the core to a lock that looks similar to a lock like this: I started by creating the outline of the face of the lock, then extruded that face. Then I created a cylinder around a portion of the core and found the difference of the two in order to get […]
