http://www.timesnapper.com/

TimeSnapper runs in the background of your computer, taking screenshots of your desktop every few seconds all week long. TimeSnapper lets you play back your week just like a movie. You can play it at any speed you like, and jump in at any time you like. When it’s time to fill out that dreaded timesheet, TimeSnapper is a savior. No need to tear your hair out trying to remember where all the time went. This has been added to the tools section of Research Resources Subject Tracer™.
