Neologizer
Neologizer analyzes the structure of words in a given text and uses what it learns to make up new words. You may find a practical use for such neologizing (filler text, brand naming, etc.), but mostly it's just fun.

Cipher Lesson
This is a simple, introductory programming lesson I designed for use with my daughter, who was about eight at the time. Each line is commented with a number corresponding to the steps outlined in the opening comment.

Key Painter
This is a fun little app I put together for Khan Academy that lets you paint with your mouse while selecting colors with your keyboard. Colors can be blended and adjusted in real time.

Bitpane (in progress)
Bitpane is a multi-pane in-browser text editor with a lot of potential. It's still in the early stages, and I've had to put this on hold for a while, but try dragging the right or bottom edges for more editor panes.
