I have a google doc spreadsheet thing. Over the last year when I've been bored or annoyed at work, I've added columns to it - percent done, percent remaining, days left, days worked this year, holidays, personal days I'm taking off, how many actual work days I have left. I guess I've been bored or annoyed a fair amount. :) Sometimes I color code it in different ways.
Because it's a spread sheet, it doesn't look too unprofessional if someone catches a glance of it on my screen.
