I haved worked on a variety of project in my spare-time, some of which I have released as Open Source. Here are a few of my projects available on Google Code:
Sore Thumb is a Django application that processes images and turns them in to thumbnails, with additional effects such as rounder corners and keylines. See /tag/sorethumb/ for more information.
PyFilesystem or (FS), is a Python module that abstracts disparate file-systems. At a basic level it simplifies file / directory access and reduces the changes of errors, but it can also be used to allow the developer to work remote file systems as easily as if they were locally. See /tag/fs/ form more information.
Django Techblog is the blogging application that powers this site. See /tag/techblog/ for posts about Techblog.
Game Objects is a Python module to simplify writing games, and includes fast Vector and Matrix classes.
Postmarkup is a Python module to translate bbcode (a simple markup developed for Forum applications) to HTML. It has grown in to a very flexible system that can be used to create simple markup languages. The content in this site is written in a Postmarkup dialect.
A Python module to parse streamed netstrings, which can form the basis of an efficient network protocol.
