Introduction
Welcome. This is the place where I’ve collected some of the things I’ve created using the Computer Science platform in the Khan Academy. Everything here (code, documentation, etc.) is released into the public domain, and available on GitHub.
Update: I no longer use the KA CS environment, and I won’t be posting any new programs. I will keep this page as a reference, but the links to the programs inside the KA will be broken. Sorry.

Programs
A simple tool that identifies elements from a chemical formula, and provides useful information about them.
A demo of a simple physics simulation based on the (now classic) paper by Thomas Jakobsen, “Advanced Character Physics”.
A simple utility to turn images into JavaScript code that you can integrate into your programs.
Spin-off of the official “Snowman” program. It adds falling snowflakes, and control of the snowman with the keyboard.
A demonstration program for SVGLite, a JavaScript implementation for a small subset of SVG, a standard format for describing vector graphics.
Short Tutorials
