Discover and remember your time usage in a non-intrusive way
I described but never implemented a system involving a Google App engine API and a python desktop component.
A simple system providing a command-line interface to fogbugz. Its original purpose was to aggregate the time tracking you already do manually using fogbugz and post it on your Facebook wall. However, it has accreted a few extra features and also includes a fogbugz access library with different features and a different interface from the library from fogcreek.
