While thinking about the idea some more, I was reminded of an app I once saw a segment about (I think on G4 or somewhere else) that is a combo of day planner and RPG. Basically, you create a character and then fill in your schedule with events and agenda items. Each item is given an experience point value, so that your character advances as you take out the garbage, do the grocery shopping or change the oil, etc.
Trouble is, I have NO idea how to track down this app. Any ideas on how I might find it?
