Odo

Description

Odo began as an attempt to write my own odometer, a counter of how much distance you travel with the mouse-cursor on screen. Since this kind of data takes some time to collect, I was more interested in when I did how much with the mouse. Later I added a keystroke-counter and a link to a local database, to be able to look up my history of activity.

The graph displays the measured values with a combination of colors, at one minute per horizontal pixel:

Upper graph:

Green: Horzontal mouse movement;

Red: Vertical mouse movement.

Lower graph:

Green: Keystrokes;

Red: Mouseclicks;

Blue: Application switches.

Since these are the basic colors, overlapping dispay results in different colors: red and green make yellow, blue and green make light-blue (cyan), blue and red make purple (magenta), and all three make white.
