“IOGraph” is a small Java program that tracks and draws the status of your mouse over a period of time. Lines are movement, circles are places where the mouse has stopped… The bigger the circle, the longer it was there.
I suspect the large density of horizontal lines in the center is due to my habit of always selecting the text I'm currently reading. It's interesting to see the areas of the screen which I don't really use (yes, this only tracks mouse activity, but my eyes usually follow my mouse).
