I came across Odoplus today which is a bit like WhatPulse for a mouse. It tracks how often you use which buttons on your mouse and where. According to the site:
Features:
- Tracks overall and intermediate distance
- Click counts for left, right, center buttons
- Now supports wheel mice!
- Graphical click distribution view
- Only needs about 500K of your RAM
- It's Freeware
If only it'd tell me how many calories I'm burning by operating my mouse
I've covered nearly 3km with my mouse…so tired now.
