I've been working on an application to track my tasks and todos. It is sort of a mashup of Google Code, Basecamp, YouTRACK, JIRA and FogBugz. I'm orienting the app for individual as opposed to enterprise deployments and hope to Open Source the whole thing when I'm done.
I recently arrived at a nice looking project/task page … so I guess I just wanted to tell somebody :) And of course, I'm drumming up ideas for iOS clents!
