Recently

geojson.io grew into a new stage of maturity. I tinkered with new interfaces and algorithms for feature extraction, camped and ran in Virginia with Kevin, and worked on quite a few fun projects at work.

Turtle

turtle was written in an hour or so after watching yet another Alan Kay video. Like mistakes.io and geojson.io it uses GitHub Gist as a backend storage mechanism.

The formula is simple: you provide a function that takes an argument ‘t’, for the step (0 to 30000), and it returns a direction, in degrees, or an array of functions that return either a degree direction or other functions. In a way, it’s a bit like tail recursion.

It hits a similar need as Turtle graphics, but I wanted to simplify one of the surfaces: drawings are coded functionally, as one number value to another and first-class functions can be used for branching, recursion, and so on.
