I have written various applications and scripts over the years, mainly in Python or PHP. Some of them are very old and amatuerish. The source of these are available:

• Play-5 - Play the strategy game "Go" over AIM or with a Flash client. Currently on hiatus pending code rewrite.
• Web Recruitment Application - A web based recruitment system for guilds of MMO games.
• Network File Searcher (Python) - This program takes a list of computers and attempts to connect to each computer and search the file system for files with a given name or file extension. Upon locating a file that fits the bill, it will copy the file to your computer. Requires each computer to be accessable through a common admin username/password (good for company networks).
• Trillian to AIM Log Converter (Python) - TrillianToAim will parse your Trillian logs and convert them to the colorful HTML format that DeadAIM and Aim+ use - just specify directories.
• Google 'Did you mean?' Generator - Just a tiny little spoof generator for making pages that look like google's 'did you mean' pages.
• CSS Analyzer - Give this script a css file and it'll give you info on the colors and classes with previews.
• Time Lapse Video scripts - Custom special effects for time lapse video.
• Mass Text Video scripts - Custom special effects to generate lots of coordinated on-screen text.
