PANE is an innovative and beautiful way to visualize what's happening while you write code. I especially liked seeing the construction of fractals! — alicia

Relit is the implementation of relatively recent research into typed literal macros: a generalization of custom literal syntax. (Any new literal type, i.e. regex literals or html literals, can be defined and exported by a library.) — charlesc

This is my solution to day 3 of Advent of Code 2018 (https://adventofcode.com/2018/day/3). I was pretty excited about this code, because it maps very cleanly to how I thought about the problem in my head when I sat down to write it. I think it's a great illustration of how nice it can be to solve problems like this in languages with built-in support for multidimensional arrays! — porterjamesj

An interactive visualization of the space of Euler spiral segments and their optimal conversion to cubic Béziers. — Raph

This blog post really clearly explains a fun concept related to probability and expected value. — alicia

Jennifer Wang built a Harry Potter magic wand that uses machine learning to detect gestures. The wand contains an inertial measurement unit (IMU) to sense position & orientation. You can watch her talk on the ML design process and find the code on GitHub. — jennifer

This is such a useful and simple tool! Use Stencilfy to write text in any font you like, and turn it into a stencil you can cut out on a laser cutter. Read more about it here: https://medium.com/@scientiffic/stencilfy-creating-laser-cutter-friendly-type-b7b8ef1831ec  — alicia

Beautiful visualization of NYC subway activity over the course of a week. — porterjamesj

It explores an interesting way to consume media, and is a great example of what you can get done in a week in an environment like RC. — porterjamesj

Have you wondered, "Hey, is the number 144 cool?" Wonder no more: this site will tell you every fun fact you ever wanted to know about a number and then some. — rachel
