Activity Logger

[edit] QuickLog
I need to track what I've been working on, but my memory's so bad that by the end of the day I've already forgotten. So I've hacked together a tiny Java Swing desktop app into which I can quickly jot my current activity (and todos), with the data being stored as RDF.
I'm putting together a view of the data using SPARQL, XSLT and SIMILE's Timgrid:

Swing app needs Java 5, has ant script also a README.
